Rihanna teamed up with Justin Timberlake this weekend to shoot a new music video for her song Rehab which also features JT on vocals. The pair amped up the sexual energy on the SoCal set of the vid enough to get tongues wagging — should Chris Brown and Jessica Biel be worried? Here are a few pics from the Rehab set:

JESSICA BIEL and CHRIS BROWN, I’d advise you to look away. Your hot other halves sent temperatures soaring with their raunchy moves on the set of the music vid for RIHANNA’s new song featuring JUSTIN TIMBERLAKE. No wonder JT is so keen to lend his vocal talents to collaborations when he gets to spend his days bumping and grinding with such sexy pop hotties as Rihanna. Though the pair are very much committed to their respective partners, there’s no doubt they struck up a sizzling chemistry on the Rehab shoot. Dressed in a dress-cum-swimming costume, Rihanna rubbed up against the SexyBack star in the blazing LA sun and bent over without inhibition. Which probably explains why Justin couldn’t resist the occasional peak at her body.
Damn. It looks like they are making a hawt-ass video. Rihanna looks amazing …that girl is all legs. I hope that JT does more than just scowl and glare at her in the vid … I wouldn’t mind seein’ a little bump and grind action betwixt these two. I thought that Rihanna and Adam Lavine from Maroon 5 looked good on screen together but they were both wearing too much clothing. I can’t wait to see how this video will turn out.
