Dakota Johnson May Love The Hills as Much as We Do—Watch and See!

Actress and model looked like they'd been friends for years

Leave it to Dakota Johnson to give us a throwback moment to The Hills that just makes us melt.

The Fifty Shades of Grey actress was filmed by none other than model-of-the-moment, Cara Delevingne, during a girls' day out and was caught singing the theme song of the MTV reality show on camera.

Johnson, who hid behind a curtain at first, then burst through belting the Natasha Bedingfield track "Unwritten." Naturally, Johnson quickly realized the ridiculousness of the Instagram clip and began laughing at herself almost immediately after singing along to the super catchy chorus.

You can even hear Delevingne giggling from behind the iPhone camera! And it looks like Johnson is just another famous face to add to the growing list of celebrities that Delevingne spends her free time with.

The Brit-born beauty has been spotted hanging out with fellow models like Kendall Jenner, Gigi Hadid and Joan Smalls, and grabbing dinners with Zoe Kravitz, Rihanna and Rashida Jones.

Clearly she's one popular girl both in front and behind the camera!
