Britney Caught Out Panty-Less...Again

Britney Spears has shocked again, flashing her panty-less private parts at a paparazzi photographer after her performance at Sunday night's MTV Video Music Awards.

Spears exposed herself while stepping into an awaiting limousine after leaving Las Vegas' Bellagio hotel, where she partied with brother Bryan after her embarrassing awards show performance.

And while she was mocked for hitting the VMAs stage in just her undies, she made headlines for taking them off later--when she was caught without her pants by a WENN photographer.

It's not the first time Spears has been caught without underwear--in November of last year Britney revealed all to a photographer during a night out with party pal Paris Hilton, just two months after giving birth to her second child, Jayden James.

Spears' gaffe came just hours after she disappointed the VMA audience with a disjointed and critically panned comeback performance of her new single "Gimme More"--her first major public appearance in four years.

A bystander tells WENN, "What is she thinking? She's a mother of two and here she is flashing her goods to the world!"
