　　I think I did it again
　　I made you believe we're more than just friends
　　Oh baby
　　It might seem like a crush
　　But it doesn't mean that I'm serious
　　'Cause to lose all my senses
　　That is just so typically me
　　Oh baby, baby
　　Oops!...I did it again
　　I played with your heart, got lost in the game
　　Oops!...You think I'm in love
　　That I'm sent from above
　　I'm not that innocent
　　You see my problem is this
　　I'm dreaming away
　　Wishing that heroes, they truly exist
　　I cry, watching the days
　　Can't you see I'm a fool in so many ways
　　"All aboard"
　　"Britney, before you go, there's something I want you to have"
　　"Oh, it's beautiful, but wait a minute, isn't this...?"
　　"Yeah, yes it is"
　　"But I thought the old lady dropped it into the ocean in the end"
　　"Well baby, I went down and got it for you"
　　"Oh, you shouldn't have"
　　Oops!...I did it again
　　I played with your heart, got lost in the game
　　Oops!...You think I'm in love
　　That I'm sent from above
　　I'm not that innocent
　　Oops!...I did it again to your heart
　　Got lost in this game, oh baby
　　Oops!...You think that I'm sent from above
　　I'm not that innocent
