Word's still out on whether Britney Spears herself will show up on "Glee" next season -- but her music definitely will!
Show creator Ryan Murphy confirmed to ET that an all-Britney episode, a la last season's "The Power of Madonna," is currently being written for Season 2 -- meaning songs like "...Baby One More Time," "Circus" and "Toxic" could all be popping up at McKinley High.
One number we're praying for -- "Womanizer," aimed right at Puck.
