She’s still Jenny from the block! Jennifer Lopez sang along to her 2002 hit while celebrating her 52nd birthday over the weekend, and yes, Ben Affleck was by her side.

Photos and videos posted to social media show Affleck — who starred in the “Jenny from the Block” music video nearly 20 years ago — whispering into Lopez’s ear while she sang along to the song at her party. The pair engaged in plenty of PDA at J.Lo’s big bash, cuddling up while guests cheered at L’Opera in St Tropez, France.

Lopez went Instagram official with Affleck on her birthday.

“5 2 … what it do,” she captioned snaps celebrating her big day, including one of her sharing a passionate kiss with the actor.

Lopez and Affleck, dubbed Bennifer, were previously engaged from 2002 to 2004. The birthday girl rekindled her romance with Affleck earlier this year, after she and fiancé Alex Rodriguez called it quits.

Earlier this week, Lopez told Hoda Kotb on the Today show that she’d be having a low-key birthday this year.

“They keep coming, these birthdays,” she joked. “[I’ll be celebrating] with friends, having fun, you know, raise a glass, give a toast.”

While Lopez was open to discussing some of her personal life, she wasn’t so inclined to talk about her rekindled romance with Affleck, only saying, “I am happy!” as she dodged questions about her relationship.
