Beyoncé & Kelly Rowland come out for Ciara's 30th birthday party (pictured together)...

Yesterday was Ciara's 30th birthday. In celebration, she hosted a star-studded Superhero-themed birthday bash right on time for Halloween. 
The bash took place at the Warner Bros. lot in Los Angeles, where Ciara and her boyfriend Russell Wilson dressed up as Catwoman and Batman. The couple reportedly took it up a notch by showing up at the party in a Batmobile.  

Beyoncé showed up as Storm from X-Men, while Kelly Rowland came dressed as Black Canary!

If you don't want anyone overshadowing you at your own birthday bash, don't invite Beyoncé! Her appearance got more coverage than the actual b'day girl.
