Watch Britney Spears impersonator Derrick Berry perform on last night's episode of America's Got Talent.

He was actually good!! Needs to work on the footwork a little bit 'cause Brit hits it harder but Derrick's totally got the mannerisms, he's even got the wink.

We'll be seeing more of "Britney" 'cause she was voted to go through to the next round.
