The Lifetime biopic Britney Ever After shows everything from Spears' start on the Mickey Mouse Clubhouse to her super stardom. We even get an inside look into her and Justin Timberlake's relationship (swoon) and of course that infamous head shave. She took an L for that, but of course it wouldn't be a biopic without showing her massive bounce back. Britney Ever After premieres on Lifetime on February 18. All hail the Princess of Pop!
