Rihanna was all smiles at yesterday???s annual Kids??? awards. Taking a break from her hectic schedule, Nickelodeon Kids??? Choice Awards 2008 was graced by her much-awaited presence. And to everybody???s surprise she and her boyfriend (supposed I guess) Chris Brown walked the orange carpet separately. As a matter of fact Chris denied being in relationship with Rihanna at all. Rihanna and Chris were not spotted together the entire night and she instead chummed it up with Ashlee Simpson. Thereafter she headed for her presenting duties with Brendan Fraser. Check out the pictures of Rihanna at the awards in the gallery after jump. By the way was Ashlee Simpson always that short? We all know that Brandon was always that weird. Just look at his face!
