Leaving it all “on the floor.”

Jennifer Lopez let loose at Bruno Mars’ concert Thursday amid her and Ben Affleck’s marital woes.

The singer, 55, was seen in a social media video throwing her arms in the air and flipping her hair while Mars sang, “It’s a beautiful night, we’re looking for something dumb to do / Hey baby, I think I wanna marry you.”

Lopez, 55, even appeared to sing, “I think I wanna marry you,” alongside the other concertgoers at the new Intuit Dome in Inglewood, Calif., Thursday night.

The “Marry Me” actress kept her look casual for the night and wore a simple, white cropped top with blue pants. She pulled her hair back into a loose ponytail and added oversized glasses, stacked bracelets and hoop earrings.

Before the show, Lopez was photographed sitting in the VIP area while laughing and chatting with Ashton Kutcher.

It’s unclear who Lopez attended the concert with, but she rocked out to Mars just a few hours after visiting Affleck’s rental home in Brentwood, Calif., on his 52nd birthday.

Lopez notably didn’t post anything on social media for Affleck on his birthday –– and instead shared a solo snap of her posing in a sheer gown.

The “Let’s Get Loud” songstress recently celebrated her birthday, as well, but she opted to spend it in the Hamptons with friends –– and no Affleck –– last month.

Lopez didn’t pay tribute to her husband on social media but, instead, posted a photo of herself on Thursday.

Lopez and Affleck sparked divorce speculation in May when the actor didn’t attend the Met Gala with his wife and moved out of their $68 million mansion and into a rental home. They then listed the property for sale in July.

Since then, Lopez has been seen house-hunting around the Los Angeles area.

A source recently told Page Six that Affleck is waiting to file for divorce from Lopez because she is “furious” and feels “humiliated.”

“She is a romantic. There are five kids involved in this. She knew they were going to blend families. She has not fully accepted it is over,” the source spilled earlier this month.

Lopez shares twins Max and Emme, 16, with her ex-husband Marc Anthony, while Affleck shares Violet, 18, Fin, 17, and Samuel, 12, with ex-wife, Jennifer Garner.

The “Wedding Planner” actress and the “Argo” star tied the knot in July 2022 after reigniting their 2002 relationship.
