Britney Spears was forced to halt her performance Wednesday during her Las Vegas show at the AXIS auditorium inside Planet Hollywood Resort & Casino after a crazed fan crashed the stage.
"Are you guys having fun?" the pop star asked, unaware of the man's presence. Dancers blockaded the man as security guards surrounded Spears. "Is something OK?" she asked. "What's going on?"
Spears' knees buckled as she clutched one of her security guards and asked, "He's got a gun?"
The 35-year-old pop princess muted her microphone before being ushered backstage. Fans chanted support as Spears made a safe and swift exit. "We love you!" they said. "We love you!"
Meanwhile, the "I Wanna Go" singer's dancers were busy subduing the fan, who had performed a cartwheel—and kicked a security guard in the process. As he attempted to break free, her dancers pushed him to the ground until more security guards hopped on the stage to intervene.
Fans chanted "a--hole" as the man was being restrained.
The man was ejected from the theater, which seats 4,600 audience members. E! News has reached out to reps for Spears and Planet Hollywood Resort & Casino for additional comment.
Prior to the show, Spears tweeted, "Feels so good to be back in Vegas!!"
The "Make Me..." singer will return to the stage this Friday and Saturday.
