What happens in Vegas, stays in Vegas - unless you are Justin Timberlake!

Then, it is all over the Internet for the world to see!

Should have been a bit more careful, bb!

JT was in Vegas last night living it up like a single man would, partying at TAO until the early morn'. He was spotted flirting with not one but two sexy go-go dancers! Witnesses say that JT was holding the attention of a "a cute blond and a gorgeous brunette" while enjoying the club, but that the party didn't stop there!

Sources say that around 2:30 in the AM, JT escorted these ladies and a huge bottle of champagne back to his suite at the hotel!

DAYUM! Jessica Biel who?

He's gonna have a lot of explaining to do when his girl gets home!
