Out from Under

This song, which tells of a suffocating, unsalvageable relationship, was produced by Guy Sigsworth. The English electronica producer has also worked with Seal ("Crazy"), Madonna ("What It Feels Like For a Girl"), Alanis Morissette ("Moratorium") and Björk ("It's Oh So Quiet"). He also co-wrote and produced "My Baby" on Circus and produced Spears' previous hit singles "Everytime" and "Someday "I Will Understand."

This was written by Shelly Peiken ("What a Girl Wants" and "Bitch"), Arnthor Birgisson ("Us Against The World") and Wayne Hector ("Flying Without Wings").
