Rihanna celebrated her 20th birthday with a cupcake fight.
The singer celebrated at Les Deux club in Hollywood, where Kanye West and Chris Brown spiced things up by hurling cakes.
‘There was frosting all over Rihanna’s face and the group was hysterically laughing almost to the point of tears,’ an onlooker tells People Magazine.
Rihanna, who has been romantically liked with Chris, 18, was treated to a special performance of Happy Birthday by the R&B singer.
Despite rumours to the contrary, Chris denies they’re in a relationship. ‘We’re just friends… we hang out,’ he insists. But a fellow partygoer described them as 'very cosy' all night.
