If U Seek Amy

This is Spears' raunchiest tune to date mainly because its title is a sneaky way of saying "F--K Me." The song has upset a number of parents who bought Circus for their young children only to find them walking around the house singing what sounds like the F word. This clever wordplay isn't totally original; both Memphis Slim and April Wine have songs called "If You See Kay."

The "ha ha hee hee" chorus is appropriate to the album's carnival theme.

This was written by the Swedish songwriters Max Martin, Shellback and Alexander Kronlund, along with the Texan Savan Kotecha. Martin, who wrote and produced Spears' first hit "Baby One More Time," also produced this track.
