Party girl Rihanna isn't turning 24 until next week, but she's already starting the celebrations off right!
On Monday night, the singer celebrated her birthday at the Heart Mansion in Beverly Hills - Caribbean style.
100 of Rihanna's close friends and family chowed down on Caribbean food and cupcakes with Barbadian flags.
There was also a bass drum player who played Caribbean music, in addition to the regular DJ.
Some of the guests included fellow musicians, Katy Perry, Bruno Mars and new friend, Chris Martin, whom she just performed with at the Grammys this past weekend.
And of course RiRi had to have a special birthday cake! The confection, which was brought out as a surprise, featured an image of Rihanna lying on her stomach in a red bikini bottom over a giant sea shell.
Also, 20 bottles of Armand de Brignac Brut Gold Champagne were presented at the party.
Cheers Rihanna, drink to that!
