The butt selfie (or rather, the "belfie") trend first exploded a few years ago, so it's safe to say celebrities had their booty-baring poses down by the time they rang in 2018.
A-listers have spent the first part of the new year showing off their acquired belfie skills on Instagram, and although we're only a few months into 2018, these belfies are already giving the belfies of 2017 and 2016 a run for their money!
Tess Holliday started 2018 off right with a snapshot of her nude backside.
Her husband also posted this same sizzling photo on his Instagram feed.
(Can you say #RelationshipGoals?)
Ashley Graham served up her best belfies for her spread in this year's Sports Illustrated Swimsuit issue.
Tabria Majors pulled a Graham and promoted her own appearance in Sports Illustrated with (what else?) a butt selfie.

Old habits die hard, am I right?
