Rihanna Celebrates Birthday With Katy Perry!

Rihanna reportedly held a pre-birthday party on Monday (13th February), where the likes of BFF Katy Perry, Bruno Mars and  Chris Martin were all in attendance.

The We Found Love singer, who turns 24 on 20th February, apparently threw a Barbados-themed bash for herself and 100 friends at swanky venue Hearst Mansion in Beverly Hills, California.

RiRi is said to have partied with newly-single Katy and the Coldplay frontman, as they feasted on a Caribbean-style dinner and cupcakes decorated with the Barbados flag - a tribute to the R&B star's Bajan roots.

A bass drum player was also present at the event to play reggae tunes, with guests also given high-end Camacho cigars in their party bags.

A partygoer told People.com: "Rihanna was dancing all night and had an amazing time celebrating with her friends."

At the end of the night, RiRi was also presented with a personalised cake - which featured a bikini-clad icing version of the S&M hitmaker laying on top of it.
