Rihanna & Justin Timberlake | On Set for "Rehab' Music Video

Rihanna teams up with Justin Timberlake (this girl gets around) to film a scene together for Rehab, the eighth single being released off Rihanna’s 2007 Good Girl Gone Bad album. The music video shoot took place earlier this week in California. Justin reportedly co-wrote the single and decided to make a cameo in the video as well. Rihanna attracts #1 singles like a magnet scoring four hits this year alone. Add Justin Timberlake to the mix and I think it’s pretty easy to see Rihanna taking the top spot yet again. Of course with Britney, Christina & Beyonce right on the heels of her stilettos, it's anybody's guess who claws themselves to the top.
