Must have been a Hills fan!

Dakota Johnson could have really used Christian Grey's piano skills on Tuesday, Mar. 3. The Fifty Shades of Grey actress belted out Natasha Bedingfield's 2004 hit "Unwritten" — as pal Cara Delevingne caught the silly moment on tape! 

"Feel the rain on your skin!" the model, 22, captioned the video via Instagram. "This beauty needs a red curtain wherever she goes x."

Hollywood baby Johnson, 25, appeared from behind a red curtain (not the Red Room!) in the funny clip, while singing the cheerful lyrics. "The rest is still unwritten!" she jokingly sang. "Feel the rain on your skin / No one else can feel it for ya."

Melanie Griffith and Don Johnson's daughter couldn't help but laugh during the impromptu performance. Clad in a black bubble jacket and jeans, she even swayed and wrapped the curtain around her face.
