Jennifer Lopez looks thinner than ever as she arrives solo at premiere of her movie Atlas amid Ben Affleck divorce rumors (but she's still wearing her ring)

Jennifer Lopez arrived solo at the Los Angeles premiere of her movie Atlas on Monday, amid ongoing split rumors between her and husband Ben Affleck. 

The singer, 54, flashed a bright smile at the event, held at the Egyptian Theatre in Hollywood, despite claims that the Argo star, 51, has 'come to his senses' about his marriage and 'knows' he needs to divorce. 

Lopez showed off her svelte physique after recently sharing she is the 'thinnest' she's ever been, as she commanded attention at the premiere while promoting the sci-fi adventure film. 

The On the Floor hitmaker put her toned arms on display in a strapless monochrome dress with a white top and black flowing skirt. 

Over the past few weeks the pair have been bombarded with reports that their two year marriage is on the outs. However, the New York native still wore her wedding ring at the premiere.

The Selena star wore her honey-toned tresses in a chic bun, and carried a simple black clutch in her hand. She further sparkled up her look with statement silver earrings and a matching necklace.

Earlier this month Lopez talked about her weight, saying she's 'in fighting shape right now.'

'I just finished a movie called Kiss of the Spider Woman, where it was all singing and dancing, which was equal parts exhilarating and exhausting as well,' she told Kelly Ripa and Mark Consuelos on Live with Kelly and Mark. 'Now, I'm ready to go. I'm the thinnest I’ve ever been. I'm in fighting shape right now.'

Meanwhile Ben was pictured on a movie set in Los Angeles on Monday, without his wedding ring. 

The actor rocked a red jacket, t-shirt, and blue jeans as he carried a cup of coffee and a black bag while exiting his trailer. 

At the premiere Jennifer also posed with her Atlas co-stars Simu Liu, 35, and Sterling K. Brown, 48.

Simu looked dapper in a white suit, while Sterling opted for a baby blue one. Both chose to go without ties.

Lopez also posed with Atlas director Brad Peyton, 45. He looked sharp in a black suit. 

Celebrity fitness trainer Tracy Anderson, 49, was also present at Lopez's premiere, and sported a button-up Chanel top with trendy bedazzled jeans. 

Briella Guiza — who plays the younger version of Lopez's character in the film — looked chic in a white and blue floral dress. 

Courtney Baxter, 30, opted for a plunging metallic gown that highlighted her enviable figure.

Jennifer's appearance at the premiere comes amid ongoing speculation that her two-year-marriage with Ben is on the rocks. 

Even though they looked cordial at his child's performance last week and happy in a car together on Sunday, PageSix has claimed Ben is over the union and is ready to divorce. 

A source told the site that the Oscar-winning Argo star has 'come to his senses' about his 'fever dream' Lopez marriage.

Apparently the star was so caught up in his love for the Atlas actress that he could not think straight, but now his head is clear and he 'knows' he needs to divorce, despite spending quality alone time with Lope in recent days.

People also made claims on Monday about how they do not align when it comes to public attention, but their source maintained that they will stick it out as they have a 'great love story.'

The two have also been looking at new homes, it was claimed, after they bought a $60M mansion together last year, though a source has told PageSix that Lopez's is only for 'investment purposes.'

'If there was a way to divorce on grounds of temporary insanity, he would,' the PageSix source said.

'He feels like the last two years was just a fever dream, and he's come to his senses now and understands there is just no way this is going to work.'

The split speculation between Affleck and Lopez comes amid reports that the pair have been 'living separately' and that Ben moved out of their $60 million L.A. home 'several weeks ago' as per Us Weekly. 

Affleck has been staying at a house not far from their giant Bel Air estate and his ex-wife Jennifer Garner came to visit.

DailyMail.com has reached out to a rep for Lopez and Affleck, but has not heard back.

In recent weeks, both Jennifer and Ben have been spotted on various solo outings. And on Thursday, she notably liked a scathing break-up post about 'lack of integrity and respect' on Instagram. 

Fans started to notice that something might be wrong with the power couple earlier this month when they had not been photographed together in almost two months.

But they had busy careers: he was filming The Accountant in Los Angeles and she was working on co-chairing the Met Gala in New York City.

Headlines that they were on the rocks made the rounds.

But then suddenly she was seen smiling at her husband when his child Seraphina was giving a performance in her school play last week.

Ben did not look as enthused.

They were seen out together again over the weekend as he drove toward a garage by Soho House in Los Angeles.

He was holding onto a cell phone that read Jennifer Affleck on the front; it is not clear if he was holding her cell phone or if he was calling her from his phone even though she was sitting right next to him.

This time they were smiling and seemed more in sync. Both have been wearing their wedding rings.

The two have a complicated history.

They first fell in love on the set of their movie Gigli and got engaged but split in 2004.

They got back together in 2021, and eloped in Las Vegas in July 2022 before having a big ceremony later in Georgia.

Eyebrows were raised when she wrote about their love in her movie This Is Me... Now, in which he appeared, and she was seen melting down alongside him in the accompanying documentary titled The Greatest Love Story Never Told.

In the documentary he made it clear he did not like his wife sharing his old love letters.

He also addressed their different approached to fame: 'Getting back together, I said, "Listen, one of the things I don’t want is a relationship on social media." Then I sort of realized it’s not a fair thing to ask. It’s sort of like, you’re gonna marry a boat captain and you go, "Well, I don’t like the water."'

Together they have been co-parenting his kids with Garner - Violet, Seraphina and Samuel - as well as her two teens with Marc Anthony - twins Max and Emme.

People also made claims on Monday about how they do not align when it comes to attention.

'They just have very different approaches when it comes to media attention,' said a source. 'Ben hates all attention and it makes him very uncomfortable. Jennifer has always had a different approach.'

It was added it is just not 'his way' to share so much of his personal life.

'It doesn’t make him happy and causes stress in his life and then in hers. There is no question their different styles clash,' added the source.

A third source, from the music world, relayed: 'She needs that expression but Affleck simply is not comfortable with it. After a while it causes tension in the relationship.

'He is more introspective and private. She likes to open her heart to her fans and to the world. This makes them considerably different, and it has been difficult in the day-to-day relationship.'

The People source was more optimistic than the Page Six source saying they will stick it out.

'There have always been clashes in their styles, how they handle issues, and their actions, but nothing has stopped their love over the years. This is a great love story,' the insider shared.

A separate source informed People on Friday that both Lopez and Affleck 'did not celebrate Mother's Day together.'

It's not the first time fans have speculated about there being trouble in paradise in the couple's marriage.
