Jennifer Lopez was the image of glamour while shopping on Saturday with Emme, 16, one of the twins she shares with her ex-husband Marc Anthony.

The sighting came amid a whirlwind of rumors that she and her current husband Ben Affleck are skidding towards an 'imminent' divorce.

Lopez, 55, and Affleck, 52, are said to be living separately, and DailyMail.com reported they have prepared divorce documents to file at a later date.

This Thursday, she quietly paid a visit to his house on his birthday - then spent that night enjoying her girlfriends' company at a Bruno Mars concert for the opening of the new Intuit Dome in Inglewood, California.

At the start of this weekend, she was seen enjoying some family time in Los Angeles with Emme, who was seen at one point carrying a bulging shopping bag. 

Lopez served up a generous helping of cleavage in a long, slinky black dress that elegantly flattered her lithe dancer's physique.

She let her luxurious honey-blonde hair cascade freely over her shoulders in silken waves, framing her luminous complexion, which she made pop with makeup. 

Accessorizing with a set of dark sunglasses, the Selena star lent the look an dash of sparkle by wearing two large gold bracelets. 

Two nights earlier, she enjoyed a girls' night out as she attended the Bruno Mars concert at the new Intuit Dome - the same day as Affleck's 52nd birthday. 

She seemingly brushed aside the marriage woes and jumped to her Instagram stories to upload a few memorable snaps that were taken during the fun festivities.

In one image, the singer struck a pose as she sat between two of her close pals, and added that text, 'About last night,' towards the top of the picture. 

In another snap, Lopez flaunted her toned midriff while wearing a cropped, white tank top as well as denim jeans while having a blast amongst the crowd during Bruno's performance. 

Her arms were thrown up into the air as she sang along as other concertgoers also did the same. 

Other celebrities were in attendance, such as Sophia Bush, Kelsea Ballerini and Meghan Trainor. 

At one point, Jennifer was seen mingling with actor Ashton Kutcher as they crossed paths at the venue. 

Also on Thursday before the Bruno Mars concert, Jennifer paid a visit to Ben on his birthday- despite Lopez spending her own 55th birthday last month without the Oscar winner.

Ben notably purchased a $20.5 million home in the Pacific Palisades last month in July - after residing in a $100k-a-month rental in Brentwood.

The Atlas actress has been staying at their lavish mansion in Beverly Hills - which has been listed on the market for $68 million.

Lopez also appeared to snub the Good Will Hunting actor as she jumped to social media - but did not wish him a happy birthday.

She was radiant in a series of Instagram snaps while posing in a sheer, Dior dress that contained shimmering embellishments.

The star paused for photos - which were taken during her time at the Hamptons last month - while standing next to a vintage convertible.

Earlier last week, a source told People that Jennifer 'is trying to find a new home to start fresh' and added the pair are 'moving on separately.'

On Monday, Lopez was spotted spending time with Ben's son, Samuel, 12, during a shopping trip in Los Angeles. The actor shares Samuel, Violet, 18 and Fin, 15 with ex-wife Jennifer Garner.

After the outing, Jennifer stopped by Affleck's abode as she dropped Samuel off, and spent some time at the house.

'Just because she's not with Ben doesn't mean that she doesn't care about his kids,' an insider informed People. 

'She always cared about them. She spent months looking for the perfect house for their blended family last year.'

The insider added, 'Now when she's back in L.A. she wants to spend quality time with them before school resumes and Violet is off to college.'

Earlier this month, a separate insider told Page Six that Jennifer is 'furious,' adding that Ben 'has humiliated her. He was the one who initiated getting back together.'

'He's humiliated her because she made a big deal that he's the love of her life. They just had two weddings two years ago. This is some kind of a record, they're not young kids.'

Amid Lopez and Affleck's marriage woes, it was also recently revealed by a source to People that Ben has been dealing with a difficult summer.

'It hasn't been the easiest summer for him either. He's just trying to stay focused and make every day as good as possible,' the insider told the outlet.

'Ben's doing well. He thrives when he's busy and he's been working nonstop. The kids are still off from school. He spends a lot of time with them, too.'

In regards to the actor purchasing a new home - which took place on Jennifer Lopez's 55th birthday - a source told Us Weekly that, 'Ben needed new energy in his life.'

'This one is more his speed. He's in a better mindset and is pushing forward,' the insider continued.

'Ben feels like he's been weighed down this year. He will always care for Jen, but he knows the marriage is done, and he wants to focus on himself right now.'

Another source close to Ben also told the publication that the star's decision to purchase the Pacific Palisades abode 'was the closure of the relationship.'

DailyMail.com also revealed divorce documents that have been 'finalized, but not yet turned in' amid the split speculation.
