The tween star was hardly recognizable in her awesome blue ensemble -- complete with gobs of blue makeup, a� short wig, and stunning dress -- at Perez Hilton's Blue Ball Birthday Celebration last night in Hollywood.

Selena totally stole the show in her futuristic flapper outfit and posed with Perez, who was wearing a giant red wig and his own impressive disco denim 'fit. The rest of the famous guests, which included Raven-Symone, Eliza Dushku, Jenna Jameson, Aubrey O'Day, as well as Real Housewives Taylor Armstrong, Camille Grammer, and Kyle Richards, all wore blue, but none did so as well as this starlet!

Selena, who attended the party without her beau Justin Bieber, tweeted about the event: "Happy Birthday @PerezHilton what a great party."

It's strange to see Selena wear something so out of her comfort zone, but we like it! Do you?
