Beyoncé, Serena Williams, Kelly Rowland Get Into Costume

For Ciara’s 30th birthday, boyfriend Russel Wilson threw her the ultimate costume surprise party along with friends Beyoncé, Serena Williams, Kelly Rowland, and many others. The couple dressed up as Batman and Cat Woman, complete with a Batmobile parked outside. Beyoncé went as Storm from X-Men; Jay-Z must have gone as the Invisible Man—he was nowhere to be found.
