J.Lo dances the night away at Bruno Mars’ concert on Ben Affleck’s birthday — with husband nowhere in sight

Jennifer Lopez cut loose on Ben Affleck ‘s 52nd birthday, dancing her heart out at a Bruno Mars concert in Los Angeles on Thursday night — but she was dancing on her own, with her hubby nowhere in sight.

In the midst of her marriage imploding, the “On the Floor” singer, 55, ironically got down to Mars’ hit song “Marry Me.” Coincidentally, Lopez has a song and movie of the same name .

A “Bennifer” fan account posted video of Lopez dancing at LA’s Intuit Dome Thursday night on X .

Lopez was also seen backstage before Mars began the concert.

Later, the “Atlas” star spent some time in the VIP area of the Intuit Dome in Inglewood, California.

She was all smiles when actor Ashton Kutcher dropped by her table to say hello.

Earlier in the day, however, Lopez was photographed leaving Affleck’s rental house in the posh Brentwood neighborhood of Los Angeles.

The visit marked the second time she was seen at Affleck’s residence this past week after months apart .

Lopez also dropped by Affleck’s house on Sunday, August 12, where she stayed for five hours following a day shopping in Century City and at Neiman Marcus in Beverly Hills with Affleck’s son, Samuel, 12, whom he shares with ex-wife Jennifer Garner .

Garner was also spotted at the Oscar winner’s house on Thursday. The pair share three children: Violet, 18, Seraphina, 15, and Samuel.

Despite the recent reunions, their rumored impending divorce still appears to be on, with Daily Mail reporting their divorce documents “finalized, but not yet turned in.”

Though Lopez made a cameo on Affleck’s birthday, he was not at her 55th “Bridgerton”-themed birthday celebrations in the Hamptons in July, nor did the two spend their second wedding anniversary together that same month.

Lopez did not post a social media shout-out to Affleck on his birthday — instead opting to share photos from her own recent birthday bash.

Mr. and Mrs. Affleck were last photographed together in May when they attended Affleck’s daughter Violet’s high school graduation .

The “Jenny From the Block” singer spent much of her summer traveling, visiting Europe and the Hamptons. Affleck was reportedly focused on his work.

Sources told People earlier this month that Affleck hadn’t had the “easiest summer” but that he is “doing well” despite the end of his marriage playing out in public.

Affleck purchased a $20.5 million LA bachelor pad in July after he and Lopez put the $60 million Beverly Hills mansion they bought last year on the market .

The “Maid in Manhattan” star is reportedly on the hunt for her own solo pad in LA.

Lopez and Affleck dated for the first time back in 2002. They engaged that same year, sparking a media frenzy as the “Bennifer” moniker was born.

After delaying their marriage, the pair split up in 2004. However, in 2021, following the end of Lopez’s engagement to baseball star Alex Rodriguez, she and Affleck reunited. They finally married in July 2022.
