In case one Britney Spears wasn't enough, there's now another taking on America.

Derrick Barry left talent judges open-mouthed when he donned a schoolgirl outfit and danced to the pop star's hit Baby One More Time.

The male impersonator, who has performed as Britney for five years, made it through auditions for America's Got Talent earlier this year with a rendition of the singer's hit Toxic.

Gender bender: The male performer danced along to Baby One More Time

Last night, he took it up a notch, showing off a toned midriff and a shockingly ample cleavage during the act.

The 24-year-old managed to win over Baywatch David Hasselhoff, who quipped: 'I'm questioning my sexuality.'

But Barry failed to impress fellow judge Piers Morgan.

Inspired: Derrick describes his idol as 'so talented'

'I don't think, personally, that grown men should be wearing school girl outfits and pretending to be Britney Spears,' he concluded.

Sharon Osbourne made up for the ex-tabloid editor's lack of enthusiasm.

'I just love you - I love Britney,' she gushed. 'I think there's room for two Britneys.'

Before his performance, Barry broke down in tears as he told the camera that troubled Britney was his inspiration.

Body of work: Derrick has been performing as Britney for five years

'There may be people or critics that don't approve of what I do, and they may not approve of her, but I'm here because she is so talented,' he said.

He added: 'Its make or break time. I think the world is ready to see that male impersonation is a true art form.'

Barry must wait to find out if he has survived a viewer vote to progress into the next round of the talent contest.

Mixed reviews: Sharon Osbourne and David Hasselhoff were impressed by Derrick, but Piers Morgan was left cold
