Beyonce chose Storm from "X-Men" as her character for Ciara's superhero-themed birthday party.
Bey posed with comedian Jeff Dye Saturday night on the Warner Bros. lot.
Ciara came as Batwoman, accompanied by Russell Wilson, who came as her Batman. And, of course, they arrived in the Batmobile.
Ciara turned 30, which explains why Warner Bros. opened its lot to her.
