What a happy surprise!
Sure, Britney didn't write any of her songs on Femme Fatale, but let's not forget, she's written some of her biggest hits, including Everytime (flawless) and her hit Me Against the Music, featuring Madonna.
We're so excited about this collab! Maybe Brit can even do some vocals on the track too??
Can't wait to hear the new song!
