Never one to flog a dead donkey, Rihanna is back with the 800th single from her almighty Good Girl Gone Bad album. It seemed inevitable that she'd team up with Justin Timberlake eventually - separately they're flaming hot, so just imagine what they'd be like together! - and thankfully it seems to have worked.

The video for 'Rehab' finds a scantily-clad Rihanna doing what looks like Pilates against a flashy convertible in the desert. When JT pulls up, he unbuttons his leathers, takes a cool shower and saunters over to her. You know it can only get better from there. The pop pair put in such a highly-charged, effortlessly sexual display that it's no surprise Justin's lady was far from happy. Still, maybe he had to make up for the fact that you have to listen very hard to hear him in this song...
