Nothing to see here!
Ever since former "Glee" star Darren Criss stripped down to his birthday suit on Instagram, we've been wondering: What other male celebrities have gone totally nude on social media?
Justin Bieber infamously flaunted his complete derrière in a since-deleted Instagram post of himself standing on a boat, while John Legend also showed his backside -- but that glimpse was brought to you by his wife, Chrissy Teigen, while Legend wasn't paying attention.
Josh Brolin also posted a photo of himself chilling without any clothes on once, while "Pretty Little Liars" stud once channeled "Mowgli 2.0" getting out of the pool after a quick skinny dipping session.
