Rihanna celebrates 20th birthday

Singer celebrates with a cake fight!

Rihanna was spotted celebrating her 20th birthday with a bash – and cupcake fight! – at Les Deux in Hollywood.

"There was frosting all over Rihanna's face and the group was hysterically laughing to the point of almost tears," a guest tells People.

When partygoers (like Kanye West and Wilmer Valderrama) weren't flinging cupcakes, they offered a standing ovation after Chris Brown sang an a capella version of "Happy Birthday".

While Brown has denied that he and the birthday gal are dating ("We're just friends ... we hang out," he told PEOPLE at a post Grammy party), a party guest tells us the two were cuddling and acting "very cozy all night."
