Justin Bieber is reportedly backing off threats to sue the paparazzo who photographed him naked -- because the photo is darn flattering.

On Wednesday (October 7) , a pic of a buck-naked Bieber on vacation in Bora Bora set off an Internet frenzy. It was taken from long distance by a paparazzo using a telephoto lens. As you might guess, the Bieb was none too happy about the invasion of his privacy, and his lawyers threatened a lawsuit.

But TMZ says Justin is backing away from that threat -- because he realizes the pic actually makes him -- well, one specific part of him -- look darn good. He's still upset, but sources say the likelihood of litigation is near zero.
