Evan Ross celebrated model Cora Skinner's birthday at new L.A. club The Beverly. They sat at an outside table filled with Skinner's friends and seemed to be having a low-key celebration. At one point, though, Ross jumped on the microphone to wish Skinner a happy birthday, calling her "baby." Paris Hilton arrived later, joining the party with her friends.
