It’s Jennifer Lopez’s birthday — and if you thought anything short of a nautical hot and heavy make-out sesh with her new/old flame, Ben Affleck, was on the table to celebrate … you were wrong.

Bennifer 2.0 have fully come out as a public couple now … and they did it on none other than her 52nd birthday — for which they’re celebrating on a yacht in what we’ve heard is in the South of France. Jen just threw up some steamy shots of herself in a bikini — and if you think they’re hot … just wait ’til you get to the last slide. Big kiss for baby Ben!!!

This certainly feels like a full-blown “we’re here” type of a moment. Until now, neither party had posted any BF/GF shots to their socials … although they have certainly been photographed together of late acting like a rekindled couple.

We’ve seen them get affectionate with each other over these past few months — even some kissing in public — but nothing quite like this … where they’re fully embracing, for the whole world to see.

As far as where they’re off to … it’s anyone’s guess. But, word is they were docked right on the edge of the bay, facing the Mediterranean — so it seems they’re gonna be on the high seas of the French Riviera for a bit. Classic celeb getaway … but means more in this context.

One last thing we’ll note … Jen definitely looks birthday/yacht ready fashion-wise, and Ben does too. He seems to have ditched his usual grey(ish) tee and cargo pants getup — opting for a nice button-down. They both look great — this may just be the photo of the year.

Anyhoo … enjoy, you two. And, congrats on hitting the big 5-2, Jenny!!!
