Jennifer Lopez and Ben Affleck (opens in new tab) have taken their rekindled relationship to the next level, sharing some *very* steamy PDA with fans.

On Saturday, Lopez (opens in new tab) was on a boat with Affleck (and her incredible abs, which she showed off in a stunning red and orange bikini that combined layers of flowing open kimono cover-up, hat, and long gold necklace) She celebrated her 52nd trip around the sun by spending a romantic afternoon.

The singer shared a small gallery of photos from the outing on Instagram. While the first three were standard #OOTD and vision board fodder (and almost every post J.Lo shares), the fourth and final image was J.Lo's best birthday present to her fans: Bennifer 2.0 (open in new tab) on her birthday! It's a steamy picture of them in the middle of making out. So. Please.

"5 2... What does it do...?" Lopez captioned the series and gave artist and photographer Ana Carvalosa (opens in new tab) credit for the photo credit.

Bennifer 2.0 technically made their Instagram debut earlier this week (opens in new tab) with a post shared by Leah Remini (opens in new tab), but Lopez's birthday PDA photo was the first time either of them posted about their own relationship It marks the first time they've done so. This is a big milestone, but not surprising considering how seriously the two have rekindled their romance.

A source recently told People (open in new tab) that Lopez and Affleck (open in new tab) are "madly in love" and consider each other "the love of each other's lives."

"Even though their split many years ago was devastating for Jennifer, she never had a bad word to say about Ben," People's source added." She believes she feels like she was given a second chance, only it wasn't meant to be at the time."[13
