Behati Prinsloo went swimming with Joe Jonas in the paradise island of St. Barth amid the rumors that her husband, Adam Levine, is flirting with "The Voice" contestant Amy Vachal.

The Victoria's Secret angel shared on Instagram a photo of her with a red towel draped around her. Not to be outdone, Joe Jonas was also wearing a red towel around his body.

Adam Levine's wife wrote, "When he tries to wear it better than me, but I know the truth!"

But there's no brewing romance going on betweent the two, said Hollywood Life.

"Before you start shipping Johati, consider that maybe Joe is in St. Barth to join him in whatever huge surprise is coming during the VS Swim Special!" it said.

Besides, Joe Jonas' ex-girlfriend, Gigi Hadid, is friends with Behati Prinsloo.

"He looks so gay! Gigi is doing better now :D" one fan commented on the photo shared by Adam Levine's wife.

The photo came on the heels of the rumors that the marriage of Adam Levine and Behati Prinsloo is in trouble as "The Voice" coach is flirting with contestant Amy Vachal.

According to OK! Magazine, there's a clear "sexual tension" between Adam Levine and Amy Vachal, as the Maroon 5 frontman has reportedly been avoiding "physical contact" with the contestant.

"No one can figure out if they've had an argument or if he's trying to skirt some sexual tension," the alleged source claimed.

But Gossip Cop that Adam Levine's marriage with Behati Prinsloo is safe since he hasn't been flirting with "The Voice" contestant.

"Adam Levine is NOT 'avoiding' 'The Voice' contestant Amy Vachal because of supposed 'sexual tension,' despite a tabloid report about his alleged 'shady behavior,'" it said. "What's worse is that OK! has put Levine in a catch-22 position. By portraying him as suddenly aloof, the singer looks like a jerk. But by suggesting there's sexual tension, he seems like a cad. Neither is remotely true."

Adam Levine and wife Behati Prinsloo just celebrated their first wedding anniversary last July 19.
