Beyoncé Hosts Party for Sis' 22nd Birthday

These ladies know how to celebrate! Beyoncé Knowles threw a dance party for Solange's 22nd birthday Monday night, at the Hollywood Hills mansion, that brought out pals Ludacris, Ne-Yo, Mario and Destiny Child's Michelle Williams. On Solange's request, the DJ kept the tunes in the family, playing nearly every hit in Beyoncé and husband Jay-Z's catalogs including "Big Pimpin'" (as Solange played a tambourine and Beyoncé showed off her best moves) and "Dirt Off Your Shoulder." When Beyoncé's "Get Me Bodied" played, revelers circled around the Knowles sisters as they reenacted dance moves from the song's video. Champagne flowed as guests noshed on barbecue chicken, cornbread, greens and mac and cheese (served buffet-style). Cupcakes with large white candles were passed through the crowd as everyone sang a rocked out version of "Happy Birthday" to Solange, who blew out the candles and banged on her tambourine.
