Fans of Britney Spears in New Jersey on Saturday got more than they bargained for – fellow pop icon Lady Gaga was in the crowd.
Spears is currently wowing the U.S. with her Femme Fatale tour, and she hit Atlantic City over the weekend. Atlantic City concert-goers were treated to two A-listers for the price of one – they went wild after Spears pointed out her pop peer in the audience.
She told devotees, "I have a very special guest tonight… Lady Gaga is here."
Sitting in the VIP section in front of the stage, Gaga stood up and waved to the cheering crowd, before dancing to Spears' set.
Gaga even stole the spotlight away from her host during a performance break – fans chanted her name and several flocked to the Poker Face singer for autographs.
Joe Jonas and Nicki Minaj opened for Spears at the show.
