Britney Spears is certainly no stranger to dancing in her music videos and on stage, but it was a bit of a surprise to see her getting her groove on during an X Factor audition recently.
Britney, who's a judge on this year's X Factor USA, was giving it some serious wellie during an audition where a young man sang Ice Ice Baby by Vanilla Ice. Brit just couldn't resist getting out of her seat for a right good boogie.
This video comes just days after her boss Simon Cowell said how surprised he was at the Oops I Did It Again singer's shyness.
"She's not on the show to be Britney Spears on a TV show," Simon explained. "She's actually there to prove to the world there's more to her, and she's got the ability to do this job really well. She's taken the role really seriously."
He continued: "It's quite interesting because when someone has done what she's done as she has with her career, and being such a public person, you kind of think she is going to be very confident, but in real life she's shy.
"There's kind of a mystique about her which I think is what kind of attracted me to her in the place."
