It looks like everyone is posting butt photos to Instagram this week.
First, Justin Bieber bared his derrière on the photo sharing platform.
Now, Chrissy Teigen uploaded a photo of John Legend's behind.
It seems Teigen did this to brag about her husband's ass and make a statement about Instagram's policies regarding nudity as topless photos of herself had been recently removed from the site.
Despite the point she was making, Teigen has done us all a great service by posting this photo.
