If You Don't Show Sidebutt This Summer You Will Be Shunned So Get It Together
Sidebutt (or "Side-butt") is now A Thing after the "Die Young" singer pranced down the blue carpet like a prized racehorse to show off how the human body reacts to infinite amounts of squat-thrust exercises. And if you think that Sidebutt is something only Ke$ha can pull-off because she's so $a$$y then check or wreck, kids, because you forgot about Gwyneth Paltrow at the Iron Man 3 premiere. Or Jennifer Lopez at the Parker premiere. Or Heidi Klum at whatever this event was. To repeat: it's a A Thing.
Adjust your wardrobe and workout routines accordingly.
