Taking to her social media account, Jennifer shared a set of sizzling bikini snaps, with one pic showing Bennifer 2.0 locking lips.
She captured the steamy album, "5 2 … what it do …💗 📸: @lacarba #birthdaymorning."
Ben and Jennifer previously dated from 2002 - 2004, after meeting on the set of "Gigli." They even got engaged, before calling it off. Shortly after her split from Alex Rodriguez earlier this year, she and Ben started being spotted together all over Los Angeles -- even hanging out together with Jennifer's kids and house hunting.
