Rihanna may be on track to earn another #1 hit, her fifth one this year. Shooting the video for her new single “Rehab” this week, Rihanna spent time with Justin Timberlake who reportedly co-wrote the single and appears in the video. Slated to premiere in early November, the pop-sensation rocked “Rehab” in a multi-colored, somewhat retro looking leotard on the beach. But the question is… will “Rehab” be another hit for the international star that has already rocked charts worldwide with “Take A Bow” and “Disturbia” ? With two other ‘it’ girls back on ‘mainstreet’ can Rihanna earn another hit. What do you think, can Rihanna hold her own against Britney Spears and Beyonce ?
