"Twilight" star Jackson Rathbone was caught up in Lady GaGa mania while out celebrating his birthday in Las Vegas - he found himself in a club surrounded by hundreds of impersonators. The actor, who plays vampire Jasper Hale in the bloodsucker franchise, turned 25 on Monday, December 21 and celebrated with a weekend trip to Sin City.

But his birthday celebrations took a bizarre twist on Friday night, December 18 when the actor and his pals arrived at Bank nightclub only to find themselves caught up in the middle of a Lady GaGa impersonator competition. The actor took it all in good humour and was spotted signing autographs and posing for pictures with dozens of GaGa lookalikes.

A source tells New York Post gossip column PageSix, "They (the impersonators) take it really seriously. People were going nuts. Especially when Jackson Rathbone showed up for his birthday."
