Britney Spears was shocked and horrified when a crazed fan rushed the stage of her Las Vegas performance last night, Breaking Celebrity News can reveal.

According to audience videos, a man crashed Spears and her dancers’ rendition of her appropriately titled tune “Crazy,” doing a flip of his own before a security guard or dancer tacked him to the ground.

After asking fans if they were having fun, the “Toxic” singer, 35, quickly became aware of the chaos behind her.

“Is something okay? What’s going on?!” she asked as a guard attempted to calm her down. “What’s wrong? What’s wrong?”

Fans cheered in support, and called the disruptor an “a**hole.”

Fortunately, Spears and her dancers appeared unhurt.

As Breaking Celebrity News exclusively reported, she will end her long-running residency later this year to focus on her family and boyfriend Sam Asghari, 23.
