Britney Spears' new album isn't due out until March 28 -- but we've got a preview of two of the songs right now!
Dr. Luke, who produced songs of Brit's new "Femme Fatale" album, leaked two samples onto his Twitter -- one for the song "I Wanna Go" late last night and another, for "Inside Out," over the weekend.
"I Wanna Go" was produced by Max Martin and Shellback, who previously worked together for "3" and "If You Seek Amy." Martin is also responsible for "...Baby One More Time" and Brit's latest single, "Hold It Against Me."
