Jennifer Lopez Enjoys Casual Solo Night Out on Ben Affleck’s 52nd Birthday

Jennifer Lopez is having some fun without Ben Affleck.
The Atlas star, 55, stepped out to watch performances by Bruno Mars and Lady Gaga and celebrate the opening night of the Intuit Dome in Inglewood, Calif., on Thursday, Aug. 15 — which is also Affleck’s 52nd birthday.

Lopez could be seen in a casual ensemble for the event in a white tank top with her hair tied up in a ponytail. She accessorized the look with large gold hoop earrings, a gold bracelet and silver bedazzled necklace that read, “Jennifer.” In photos, she could be seen laughing while sitting down and chatting with Ashton Kutcher.

She was also spotted hanging out backstage before the “Leave the Door Open” singer, 38, took the stage and was seen in high spirits in the VIP area of the venue during the show, which saw Bruno Mars and Lady Gaga perform their new duet “Die with a Smile” live.

The Air actor, 52, was notably missing from the event and was not seen with Lopez as she roamed the new event space and chatted with friends.

Earlier in the night, Lopez shared a look at herself in full glam on Instagram. In the photo, she appeared solo in a Dior dress with a sheer wrap design with a black belt tied around the waist that featured silver embellishments in a vertical pattern. She paired the look with a sleek ponytail and silver drop earrings.

This comes amid reports that the couple are experiencing tension in their marriage. Sources previously told PEOPLE in May that Lopez and Affleck’s marriage “is not in the best place at the moment” and they were living separate lives.
