Dakota shot to fame thanks to her role in box office hit, Fifty Shades of Grey, and while it's not known how long the pair have been friends, there's obviously no bad blood between the pair.

Cara, who is trying to establish an acting career, was rumoured to also both be up for the lead role of Anastasia Steele in the erotic adaptation, but ultimately lost out to Dakota.

The girls are both in New York where Cara has been also spending time with her rumoured new girlfriend, Grammy Award-winning artist St. Vincent - also known as Annie Clark.
