Who knew Britney Spears [1] was such a prankster? The singer made a hilarious appearance on Neil Patrick Harris [2]'s new variety show, Best Time Ever, on Tuesday. In the skit, Britney pretends to interview potential new bodyguards while doing and saying whatever Neil and his accomplice, Joe Jonas [3], tell her to. As the bodyguards meet the pop star one by one, Britney complies with a slew of hilarious orders, including juggling water bottles, demanding they kiss her hand, and introducing herself by saying, "It's Britney, b*tch." Watch the funny clip above, then check out Reese Witherspoon's terrifying appearance on the show earlier this month [4].
