Congratulations to Rita Ora - yesterday she hit the number ONE spot in the singles chart with I Will Never Let You Down, and today it is revealed that she will be involved in the Pepsi MAX Beats of the Beautiful game album alongside Kelly Rowland and Janelle Monáe - not a bad week, is it?

At the weekend Rita Ora also showed off her mega fit body by taking to the stage at London's G-A-Y nightclub and stripped down to her Calvin Kleins.

That's right, Rita whipped off her androgynous white shirt and black tailored trousers, to reveal a matching set of Calvin Klein undies. Well, it is all the rage these days...
