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 ʙuттon-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.
