Well, that makes it social media official! Supermodel Irina Shayk and Bradley Cooper have been dating for nearly a year but they've tried not to flaunt their relationship in the public eye, save for maybe when they get caught in a steamy make out session on the beach.

On Friday, though, she did something she hasn't done since they began their romance: she posted a photo with him in a hot tub.

The selfie cuts off their faces, but it's clear to see that it's Irina and the "American Sniper" actor. She didn't caption the snap, leaving much to the imagination.

The photo shows the brunette beauty in the forefront of the shot, wearing a low-cut, lace-up blue swimsuit that very clearly shows her cleavage. She leans up against a shirtless B Coop, his arms stretched out along the hot tub.

His chest and toned arms are unmistakable as water rises up to his chest.

The couple made their first red carpet appearance together last month at the L'Oreal Red Obsession party during Paris Fashion Week. There, the couple snuck a few kisses and acted very much like a giddy couple.

Prior to that, many wondered if the duo had split after he was spotted at breakfast with model Naomi Campbell in late February. However, it turned out that he and Naomi are longtime friends. Just days after that breakfast the actor was spotted arm-in-arm in Paris with Irina.

Photos showed that the low-key couple hadn't skipped a beat, despite the fact that they hadn't been photographed together in a month at the time.

Bradley and Irina appeared comfortable and at ease as they strolled through Paris, where he has an apartment.

The actor arrived alone in Paris on March 2, taking a car to a local hotel to pick up Irina. The two then made their way to his apartment, disproving the split rumors.

The two first got together in April 2015 and were often seen together out and about. Sometimes they were even pictured with Bradley's mom, as well, proving that mommy dearest fully approved of the romance.

Irina's new image proves that things are going rather, well, swimmingly between the two.
