Butts continue to break the internet. In the latest battle of the bums, Chrissy Teigen pits John Legend cheek-to-cheek with Justin Bieber in arguably the most popular Instagram posts of the week (John Legend’s butt is at 172K likes, which pales in comparison to Justin’s [very pale] butt at 2 million). All of this, of course, is coming off the heels of Marc Jacobs’ accidental belfie (which he reacted to in the best possible way).

We’re happy to see the boys getting a little cheeky on Instagram, since typically female celebrities are the queens of the belfie. Here’s a look back at some of the best celebrity butts on Instagram including Lady Gaga, Rihanna and (of course) most of the Kardashians.
