Leona Lewis goes reggae for Rihanna cover

Leona Lewis has been mixing it up lately. When she hasn't been out in crazy-boob-tops she's been talking about branching into dubstep, and now she's gone reggae and has covered Rihanna!

Leona performed on Radio 1 to launch their Hackney Weekend 2012 - a massive outdoor festival to celebrate the launch of the Olympics.

It'll all happen in Hackney Marshes on June 23rd and 24th, and Leona and Plan B are set to grace the stage so far.

Anyway, we digress. Leona gave her own single Better In Time a reggae twist, and mixed in a cover of Rihanna's Man Down.
