Channing Tatum posts naked shower pic after losing bet to girlfriend Jessie J

If there's one thing Channing Tatum is known for - aside from the numerous blockbusters he has starred in - it's his incredibly chiseled physique.

And yesterday, the Magic Mike star delighted fans with an unexpected snap of said chiseled physique.

But there's actually a very funny reason behind the post - basically, Tatum lost a game of Jenga, and in turn, lost a bet he had with his girlfriend Jessie J.

Check out Jessie's cheeky Instagram message to Channing:

He captioned the image: "I lost a game of Jenga to Jessica Cornish. "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..."

This was his forfeit:

The Magic Mike star left practically nothing to the imagination in the provocative snap, leaving his many admirers more than a little thrilled - not least Jessie J herself.

"Sharing is caring," the Jenga victor wrote alongside a fire and heart eyes emoji.

Needless to say, the comment section was inundated by fans who certainly weren't complaining about the 39-year-old hunk being crushed in a game of Jenga.

"No no, you keep playing Jenga. Sincerely, everyone," Instagram user @ashlee_.loraine wrote on behalf of the entire world.

"This was the first photo on my Instagram this morning! HAPPY THURSDAY LADIES," @make_it_all_sparkle_ chimed in.

Jessie J also received her fair share of praise in the comments, with many applauding the 31-year-old singer for her very giving nature.

"Always thinking of other [sic] @jessiej that's what I like about you," @kaylareneela_
