AFTER CHRIS BROWN GOT SENTENCED RIHANNA PARTIES IT UP WITH QUEEN LATIFAH & SERENA WILLIAMS!

Chris who? Rihanna hit the dance floor Tuesday night after hearing that her ex, Chris Brown, was handed a restraining order that will keep him away from her for five years.
RiRi and her gal pals flocked to downtown club Greenhouse, where they met Serena Williams, Queen Latifah and Paula Patton. "Rihanna was dancing all night," says a spy. "Chris looked like the furthest thing from her mind."

It seems that Brown's sentencing was the furthest thing from his mind: The scorned singer showed up at a West Hollywood hot spot and did an impromptu tribute to Michael Jackson just hours after he left court.
