I'm so slow sometimes

Britney Spears, no matter what you do, you always seem to weasel your way into my heart.
I just discovered this song on her Blackout album. Yes, I am aware this came out last year. And to think there was a time when I drove an hour to Alexandria, LA to buy Britney on the day it came out because the sorry excuse for a music store in my college town didn't have it.

Maybe in another year or two I will discover the amazingness on Circus. Anyone heard it yet?Recommendations?

EDIT: Even if you aren't a Gossip Girl fan, this is hot (and of course way outdated if you are a fan) and it turned me on to her new song. I cannot look at Chuck Bass the same and I think because of this video, he owns a small part of my heart
