Selena Gomez — Butt Cheeks & High Heels

0304_selena_gomez_suit_akm_gsiIf Selena Gomez was trying to find a way to make Justin Bieber REGRET breaking up … this hot red outfit will probably do the trick.

Gomez — and her butt cheeks — were hanging out in Palmdale, CA this week … where word on the street is that she was shooting a new music video.

Muy bien.
