Selena Gomez just dropped her sexiest music video ever! The 23-year-old singer released the Alek Keshishian-directed video for her single "Hands to Myself" on Monday. In the video, Gomez plays an obsessive stalker to a Hollywood hottie and is dancing around his apartment in nothing but a black bra and high-waisted booty shorts, showing off her killer curves.

She and the blond Hollywood hunk take part in some steamy make out sessions and towards the end of the video, she even strips down to nothing while she lays in his bath tub. So who is this mystery man she's obsessing over? It's Los Angeles-based male model Christopher Mason, whose photo she shared on Instagram a few days ago. His real name is Chris Brown and he is signed to Wilhelmina Models, according to The Hollywood Gossip.

Apparently, when Gomez's ex, Justin Bieber, saw her racy music video, he couldn't believe how incredible she looked and couldn't stop watching it. "At first, [Justin] didn't want to watch it because he already knows how sexy Selena is, and in the clip she ramps up her sex appeal even more," an insider told Hollywood Life, explaining that he had the video on repeat. "He has now watched it, and he keeps it close to watch again. It is almost something he is doing to keep tabs on her. He is thinking about her because he is just jealous he can't have her right now. The second she pays attention again, he will have gotten his way."
