A bet's a bet, in fairness.

Jessie J and Channing Tatum have been keeping their relationship pretty quiet but it's fair to say that this latest move means the cat is well and truly out of the bag. Channing shared a nude photo of himself in a shower last night, telling fans that Jessie'd made him do it. Posting to Instagram, the actor explained that Jessie had chosen the photo as part of a forfeit.. "I lost a game of Jenga to Jessica Cornish," he wrote. "The loser (me) had to post a picture the other person (Jessica Cornish) picked... Smh and fml... I’m never playing Jenga with her ever again..." In response, Jessie commented "Sharing is caring". Which it absolutely is, to be fair. The post blew up, drawing comments from fellow celebs including Halle Berry, Bear Grylls, Sarah Hyland and Nina Dobrev.

"I think you just broke the internet," Olivia Culpo wrote. "God damn...look at those QUADS!!!!," commented Dax Shepard.

It comes days after Jessie shared the first selfie of herself and Channing together. She posted the cute picture to her stories in honour of her fella's 39th birthday. He also shared a photo of her back in March for her birthday, along with a very cute message. "You came into this world on this day and lit it on fire. "You have blessed our eyes, our ears, our hearts and our lives. So thank you for just being you. You are so very special." Ahhhh.
