Hilaria Baldwin podcast Mom Brain is 'no longer active' as she and husband Alec ...

Hilaria Baldwin's podcast Mom Brain is 'no longer active.'

Mrs. Baldwin's audio show with Daphne Oz hasn't aired since December 2020 and doesn't appear to be coming back any time soon, as the trademark expired June 2, 2021, according to The Sun.

This news comes as Hilaria, 37, and husband Alec, 63, mourn the death of cinematographer Halyna Hutchins from a firearm accident on the set of the film Rust. 

It appears the podcast's production company Vaynerstudios, LLC and The Gallery Media Group 'abandoned' the project, as trademark paperwork obtained by The Sun states the office 'did not receive a response to the previous Office action within the six-month response period.'  

Further signaling the end of Mom Brains: the fact Hilaria removed the project from her Instagram bio.

While an episode hasn't been posted since December 23rd 2020 - around when Baldwin made headlines for allegedly faking a Spanish accent and lying about her heritage - fans took to Apple Podcasts review section to ask about the show.

'Miss you guys. When are you coming back with new episodes?' one wrote.

Another commented: 'Love the show. When is it coming back?'

A third said: 'I am missing both Daphne and Hilaria, please come back! I enjoy your topic and conversions and as an American living abroad, I feel at home listening to my 'friends.'

A fourth fan wrote: 'I miss Mom Brain! Come back ladies!' 

It's been a tough year for the Baldwins, who were first embroiled in a scandal over Hilaria allegedly misrepresenting her Spanish heritage before Alec's recent involvement with a gun accident which killed cinematographer tk and injured director tk on the set of the film Rust.

The mother-of-six took to Instagram to pay tribute to Hutchins on Monday, writing: 'My heart is with Halyna. Her husband. Her son. Their family and loved ones. And my Alec. 

'It's said "there are no words" because it's impossible to express the shock and heartache of such a tragic accident. Heartbreak. Loss. Support.' 

Alec accidentally killed the 42-year-old cinematographer on the set of their movie Rust in Santa Fe, New Mexico, on Thursday. 

Baldwin was rehearsing drawing his gun across his body when it went off. He thought the gun was loaded with blanks, after being told 'cold gun' as Assistant Director Dave Halls gave it to him.  

Halls admitted to police that he didn't check every barrel of his gun but 'should have' before he handed it to him on the set of Rust last week, and that he only looked at three of the five chambers in the weapon. 

Halls' bombshell admission is in a search warrant that was unsealed by the Sante Fe County Sheriff's department and issued on Wednesday afternoon. 

It contains details of Halls' interview with the cops, and what Hannah Gutierrez-Reed told them too. 

Halls said Gutierrez-Reed, 24, handed him the weapon and ordinarily opens it, 'spins the drum' to show him the ammo and he declares it safe. 

On Thursday however, he said he 'couldn't remember' if she spun the weapon, and that he could only remember seeing three dummy bullets, identified by hole in the side of their cartridge. 

'David advised when Hannah showed him the firearm before continuing rehearsal, he could only remember seeing three rounds. 

'He advised he should have checked them all but didn't and couldn't recall if she spun the drum,' the search warrant says.

Baldwin was handed the gun and it fired in the direction of Halyna Hutchins and Joel Souza. Hutchins died and Souza was hospitalized. 

Afterwards, Halls brought the gun back to Gutierrez-Reed and told her to open it for him. 

They then realized there were four dummy rounds and one spent live round.

'After the accident, Halls picked up the firearm from a pew inside the church and took it to the armorer. Hannah then was told to open the gun so he could see what was inside. 

'He advised he could only remember seeing at least four dummy casings with the hole in the side, and one without the hole. 

'He advised this round did not have the "cap" on it and was just the casing. David advised the incident was not a deliberate act,' the search warrant reads. 

The warrant also describes how Hannah Gutierrez-Reed described there never being 'any live rounds' on set. 

'Hannah advised that she checked the 'dummies' and ensured "they were not hot rounds". 

'She said as the crew broke for lunch, the firearms were taken back and secured inside a safe on a prop truck on set. 

'During lunch, she said the ammo was left on a cart on the set and not secured. 

'After lunch, [property manager] Sarah Zachary pulled the firearms out of the safe inside the truck and handed them to her.

'She advised there are only a few people that have access and the combination to the safe. 

'Hannah advised that she handed the gun to Alec Baldwin a couple of times, and also handed it to David Halls.

'Hannah said no live ammo is ever kept on set.'  

The revelation comes less than an hour after prosecutors revealed 'no one has been ruled out' when it comes to criminal charges.   

At the press conference on Wednesday, Santa Fe County Sheriff Adam Mendoza said all three could face charges and are still being interviewed. 

'We're going to continue interviewing getting the facts... he is an active part of this investigation we're still investigating... no one has been ruled out,' Mendoza said.

District Attorney Mary Carmack-Altwies said it was too early to bring charges but 'all options are on the table at this point.' 

Mendoza revealed the gun Baldwin fired was a Pietta .45 long colt revolver. There was other ammunition in the gun when they recovered it but it's unclear what type of ammunition that was. 

Cameras were not rolling when the accident happened and there were 16 people in the church-set where the scene was being filmed when it happened. 

The bullet that killed Hutchins was taken from Souza's shoulder and is a lead bullet. It is being taken to the FBI lab in Quantico for more examination, and officers have recovered its spent shell casing.

The 500 rounds recovered from the movie set comprise or 'blanks, dummies and live rounds.' Sheriffs would not say how many of each were recovered, or how the live rounds got to set. 

'We suspect other live rounds were filmed on this set. I won't comment on how they got there, but we suspect they are there. There was some complacency on this set and there were safety issues,' Mendoza said. 

The comments come amid a wave of complaints from TV and movie industry insiders who say Halls was negligent on safety rules on previous shoots. There have also been questions about Gutierrez-Reed's experience.  

'There are several individuals that need to be interviewed,' Mendoza said. 

According to an insider with knowledge of the set, several crew members on the set had taken several prop guns out the morning of the incident to go 'plinking' - a hobby in which people shoot at beer cans with live ammunition to pass the time.

The individual, who spoke on condition of anonymity to The Wrap, added that the round of unsanctioned target practice occurred last Thursday, just hours before Baldwin discharged one of the weapons and shot both Hutchins and Souza.   

The weapon was one of three prop guns that the film's rookie armorer, Hannah Gutierrez-Reed, 24, had set up outside the set location on a gray cart, in the desert near the city of Santa Fe.

Souza, 48, was seen for the first time Tuesday since his release from hospital following the shooting. 

He looked distraught as he sat in a car in Palo Alto, California with a female companion.

Souza, who was shot in the shoulder in Thursday's tragedy, was released from the Christus St. Vincent Regional Medical Center in Santa Fe on Friday.

He was seen near his San Francisco home Tuesday, holding his head in his hands in the passenger seat ahead of a press conference scheduled for Wednesday, at which more details of the accident will be revealed.

Hutchins, 42, died of her injuries when Alec Baldwin, star of the Western film, shot her dead in rehearsals. Affidavits containing statements from Souza and camera operator Reid Russell state that Baldwin was handed a prop gun and was told it was unloaded.

Souza told investigators with Santa Fe County Sheriff's office that he heard 'what sounded like a whip and then a loud pop.'

He noticed Hutchins grabbing her midsection as she stumbled backward. 

She 'was assisted to the ground' by other crew members and Reid Russell, a camera operator, recalled Hutchins saying she could not feel her legs. 

Souza on Saturday issued a statement, saying: 'I am gutted by the loss of my friend and colleague, Halyna. 

'She was kind, vibrant, incredibly talented, fought for every inch and always pushed me to be better. My thoughts are with her family at this most difficult time.

'I am humbled and grateful by the outpouring of affection we have received from our filmmaking community, the people of Santa Fe, and the hundreds of strangers who have reached out….. It will surely aid in my recovery.'  

According to search warrant executed by the Santa Fe County Sheriff's office last week, Gutierrez-Reed was the last person to handle the gun, leaving it along with the two other revolvers unattended on the cart in the early hours of October 21. 

It is at this point, the insider reveals, that a group of crew members took the weapons without the director and first director's knowledge, and forgot to unload the firearm in question.  

Representatives for the production of Rust did not immediately respond to DailyMail.com's request for comment on the matter, but in a previous statement issued to multiple outlets, Rust Movie Productions said: 'The safety of our cast and crew is the top priority of Rust Productions and everyone associated with the company. 

'Though we were not made aware of any official complaints concerning weapon or prop safety on set, we will be conducting an internal review of our procedures while production is shut down. 

'We will continue to cooperate with the Santa Fe authorities in their investigation and offer mental health services to the cast and crew during this tragic time.'

However, an actor on the film's set directly contradicted the company's statement, revealing to TMZ Tuesday that filming often felt 'life-threatening' - a sentiment that was then echoed by other members of the production. 

The actor, Ian A Hudson, told to the outlet that he felt particularly terrified filming a scene where his character was gunned down by a crowd of other actors using nearly a dozen guns - all of which were real.   

'I actually did feel the blanks hitting my face and my body. I could feel the wind from the shotgun being discharged,' the actor said, 'It was heavy. It was strong … It was life-threatening. It felt too surreal.'

It comes as the head electrician on Baldwin's Rust shared the final photo of Hutchins filming on set in the church in which she was shot dead.

Serge Svetnoy was standing next to the cinematographer when she was killed during rehearsals as Baldwin practiced drawing the weapon in the church pew and it accidentally fired.

The experienced crew member has since described the harrowing moment he held his friend in his arms as she lay dying while she bled over his hands.

She was shot in the chest, while director Joel Souza was also wounded, and she stumbled back before collapsing, saying: 'I can't feel my legs.'
