Inside Jennifer Lopez, Ben Affleck's Romantic Birthday Getaway In St. Tropez: 'Beautiful Trip'

Jennifer Lopez had a blast on her birthday with Ben Affleck and some of their friends, a report has revealed.

The "Justice League" star and "Hustlers" actress enjoyed a romantic getaway in St. Tropez for her 52nd birthday celebration. They also visited the nightclub L'Opéra and celebrated the occasion with an intimate group of friends.

"They are having a beautiful trip," an unnamed source told People. "They celebrated Jen's birthday at a club last night. She looked gorgeous and very happy."

The lovers reportedly cozied up to each other in a booth and even sang along to her 2002 single "Jenny from the Block," which featured Affleck in the music video. Also, Lopez and Affleck did not shy away from packing on the PDA during the sighting even if they were surrounded by their fans and friends. The two were photographed kissing and cuddling.

Affleck and Lopez did not just sing along to the song, they were also photographed redoing the iconic scene from the music video where he grabbed her booty while aboard a yacht.

"So Ben Affleck is looking hot and awake… all he needed was that booty to bring him back life! thanks @JLo doing the Goddesses work," one tweeted.

"This is deranged but also brilliant but also ridiculous but also fascinating," author Zeba Blay said of the photos showing Affleck touching Lopez's behind over the weekend.

Lopez and Affleck rekindled their romance in May, just weeks after she and Alex Rodriguez called off their engagement in April. Lopez and Affleck have been spotted out and about in the past weeks, but they never addressed their status. But on her birthday, Lopez made their relationship Instagram official by sharing a series of bikini photos. She also included a photo of her and Affleck passionately kissing each other.

"5 2 … what it do," she wrote in the caption.

Lopez and Affleck are "madly in love," an unnamed source told People adding that they are the "love of each other's lives."

"Even though their split many years ago was devastating for Jennifer, she has never had a bad word to say about Ben. She believes that it just wasn't meant to be then and feels like they've been given a second chance," the tipster shared.
