Yeah, I kinda figured that when I first heard the song.
But I don't get peoples deal with the song. There's a ton of hidden messages in the Britney songs if you know where to look. Examples: Toxic which if you think about it could be talking about drugs. Hit me baby one more time. Hello? talk about hidden messages. And I'm a slave for you. Enough said on that one.
At least If U Seek Amy hides it better.
