Britney Spears' bodyguards and dancers earned their salaries Wednesday night, stopping a man who snuck onstage in Las Vegas, where the singer has a residency at Planet Hollywood, TMZ and Las Vegas' KNTV report.

A bodyguard standing to Spears' right noticed the man from across the stage and tried to get the singer's attention as she performed Crazy. But she didn't seem to catch on until her dancers and other guards had him pinned down.

Informed of what had happened, Spears' knees briefly buckled as she asked the guards if everyone else was OK and whether the man had a gun. She was then ushered backstage while the man was handcuffed and escorted out and then later resumed the show.

The Las Vegas Metropolitan Police Department and Planet Hollywood's parent company, Caesar's, did not immediately respond to USA TODAY's query about whether the man's identity and whether he was arrested.

Wednesday was Spears' first show back after a summer tour of Asia, she noted in a tweet earlier that afternoon.
