Justin Bieber's usually in front of the lens, but Friday he played photographer at a bathing suit photo shoot with his ex, Chantel Jeffries. The Miami-based model posed in a sexy one-piece for the Biebster, as he trained his lens on her back side. The bathing suit label, San Lorenzo Bikini, shared some photos on Instagram, as did Chantel.

Justin and Jeffries date back to early last year, when the two hooked up in Miami for some post-New Year partying. In fact, their raging landed Justin in jail for the night on Jan 23, when he was caught drag racing with marijuana and Xanax in his system.

The Biebs' later brought Chantel back to LA with him, briefly, before the pair jetted off the Panama for another vacation. All the while, Bieber fans and Selena were crying ... just like they are today #JealousMuch!
