A famous transgender YouTuber is facing fresh allegations of racism days after they were accused of having 'inappropriate relations' with a child.

Ava Kris Tyson, 28, who rose to fame as a co-host on the wildly popular MrBeast YouTube channel, quit social media on Tuesday and apologized for her behavior — after it emerged that she had sent risque messages to a child, whom she allegedly began an online relationship with when the person was just 13.

Now, Tyson has come under fire for a series of racially insensitive social media posts, as well as for using the n-word in a recently resurfaced livestream video.

In one post, Tyson appears to joke about police brutality and in another, the YouTuber calls Islam a 'backwards religion that hates anything different.' 

Critics of Tyson's racial comments have been making their voices heard since at least last year, including TikTok user @ibaad.khuram0, who posted a pair of Tyson's Islamophobic tweets dating back to May 2017.

Reacting to the Manchester Arena terrorist bombing from that month, perpetrated by a suicide bomber with reported ties to the Islamic State (ISIS) and an Algerian-wing of of al-Qaeda, Tyson tweeted, 'Why the f*** do we even take Islam serious?'

'It's an old *** backwards religion that hates anything different and treats women like shit. Why the f*** do people still accept it,' Tyson asked.

Scores of TikTok users flocked to the post, with comments demanding an apology and others saying 'This is why you shouldn't have a celebrity role model.'  

Still earlier, in a Twitter feud from 2016, Tyson appears to bicker in public with a black user on the platform over how to properly cook a steak: 'Look at all the black people who have never had a steak that's more than 10$' Tyson wrote.

And in another instance, the young YouTube personality posted an inflammatory meme from the Instagram account @defectsofcharacter which could be interpreted as either a critique or an endorsement of racist police brutality against Black people.  

'When you gotta shoot hoops at 3:00 and black kids at 4:30,' the meme image reads, accompanied by a white male police officer holding a basketball.

The tweets have resurfaced alongside more vivid accusations of using a racial slur, clearly audible in a clip apparently from one of MrBeast's 10-hour livestreams.

The date of the video is unknown, but it was taken when Tyson was in his 20s.

Tyson can be heard using the n-word and justifying the racist slur by saying 'but I'm not relevant.'

In the grainy and short video, Tyson seems to be speaking to MrBeast, who appears to be joking with him remotely on camera. 

'You do know that I'm watching this for 10 hours straight on a livestream,' MrBeast warns Tyson in the video clip, after the racial slur is uttered. 

Tyson is a childhood friend of MrBeast, whose real name is Jimmy Donaldson, collaborating with the content creator on his runaway success YouTube channel, which has earned Donaldson a net worth of $700 million.

Donaldson, whose channel is known for his extravagant stunts and philanthropic initiatives, has yet to comment publicly on the allegations against Tyson.

Nevertheless, a former MrBeast employee named Dawson posted a video to TikTok alleging that 'Kris is the tip of the iceberg' and that 'MrBeast knew.' 

On Tuesday, Tyson said she would be stepping back from her role as a presenter and co-host on the channel. 

In an X post that day, Tyson wrote: 'I would like to apologize for any of my past behavior or comments if it hurt or offended anyone. It was not my intent.'

'Seeing recent events we've mutually decided it's best I permanently step away from all things MrBeast and social media to focus on my family and mental health.'

The initial allegations against Tyson this week stemmed from interactions with a then 13-year-old who goes by the name 'Lava' online. The pair were allegedly introduced after the child won an online competition.

Tyson — who has a son with her ex-wife — is said to have spent years communicating with the fan on public online forums before meeting in person when the teen turned 16 years old.

Lava, the fan at the center of this controversy who is now an adult, says they are not a victim and has defended Tyson but has admitted some of the messages were 'inappropriate' and 'edgy.' 

Tyson was one of four friends hired by the content creator to help run his YouTube channel, along with Chandler Hallow, Garrett Ronalds and Jake Franklin. 

Appearing in numerous MrBeast videos alongside Donaldson, she has participated in many challenges and prank videos made for the channel. 

Tyson had also become the main host of the channel Beast Reacts (formerly known as BeastHacks).

Nevertheless, since the relationship was first revealed in a series of expose-style videos and clips, more controversial posts by Tyson have continued to resurface. 

Tyson referred to an image of the 14-year-old character from the Incredibles, Violet, as 'low key cute,' while other posts included references to them wanting to be a part of sexual relations with children.

In 2016, they posted 'nothing gets my k*** cranking like some Loli' - the term refers to a young-looking girl character.

They also commented on a link posted on what was then Twitter that redirected users to a pornographic comic of Caillou and his mother - 'Caillou' is a popular children's show about a four-year-old boy.

'Help, I need an adult,' Tyson commented.

MrBeast was also said to have connected KEEMSTAR, who hosts the show DramaAlert, with Lava, promoting a second statement that refuted the allegations against Tyson.

'Lava ' I was NOT groomed by Kris Tyson,'' KEEMSTAR shared on X.

'Lava ' I did not meet Kris Tyson by myself I meet Kris & the MrBeast crew with my family present.'

'Lava ' I ran a discord with Kris Tyson when I was 13 and edgy inappropriate jokes were said that's it.''

However, Jake Franklin, a former member of MrBeast's channel, posted 'Jimmy knew' on X after news about Tyson broke.

MrBeast's real name is James Stephen 'Jimmy' Donaldson.

But Franklin's post was vague and cannot be confirmed in relation to the allegations against Tyson.

Tuesday evening, an account on X apparently owned by Lava reiterated the denials posted by KEEMSTAR.

'I am not a victim and I am not backpedaling any statements I have already made,' the post from @LavaGS reads. 'Nothing bad happened between me and Kris, people are creating lies around my name.'

MrBeast has not released an official statement about the allegations or responded to DailyMail.com's questions.
