Britney Channels Her 2002 Self?!?

Britney looked, dare I say it, hot (?) leaving Opera Nightclub in LA last night. Sure she was wearing sunglasses in the dark, no bra, a dumb hat and what we all know is a wig -- but still. Golf claps for Brit Brit. Whether or not she made that supposed whirlwind trip to Europe, she was definitely not feeling the effects of jetlag. Even though it's not much of a dance track, I wonder if the DJ was gutsy enough to spin Britney's new song in the club? Maybe mixed in with a little Toxic?
