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.
