Lady GaGa attracted a star-studded crowd to her gig at the Wiltern Theatre in Los Angeles on Friday (March 16th).
US rapper Kanye West and celebrity blogger Perez Hilton both watched on as Lady GaGa played hits from her debut album 'The Fame'.
Hilton joined the singer on stage at one point, describing her as “the new princess of pop”, according to Rolling Stone.
Her setlist included new single 'Poker Face' and the worldwide smash hit 'Just Dance'.
The gig, which was the second date on the singer's US tour, once again saw Lady GaGa showcase her new bubble wrap outfit.
The Fame Ball Tour will call at venues across across the US and Canada throughout the spring.
