Cara Delevingne Opens Up About Girlfriend St. Vincent: 'Being In Love Is Why I'm So Happy'

Cara Delevingne has opened up about her relationship with girlfriend St. Vincent for the first time, telling the world that she's in love!

"I think that being in love with my girlfriend is a big part of why I'm feeling so happy with who I am these days," she says in the new issue of Vogue.

Adding: "And for those words to come out of my mouth is actually a miracle."

The supermodel and budding actress explains that she's not just into women, as she describes a recent dream she had...

"It took me a long time to accept the idea, until I first fell in love with a girl at 20 and recognized that I had to accept it," she explains.

"I have erotic dreams only about men," she admits. "I had one two nights ago where I went up to a guy in the back of a VW minivan, with a bunch of his friends around him, and pretty much jumped him."

The Paper Towns star goes on to add that she's actually really scared of relationships.

"Women are what completely inspire me, and they have also been my downfall. I have only been hurt by women, my mother first of all," she says.

"The thing is, if I ever found a guy I could fall in love with, I'd want to marry him and have his children. And that scares me to death because I think I'm a whole bunch of crazy, and I always worry that a guy will walk away once he really, truly knows me."

While on the subject of her Paper character Margo, Cara reveals she actually helped her break up with a boyfriend. 

"I'm no Method actor. I've tried staying in character, and it's just exhausting," she says.

"But after playing Margo, I broke up with my boyfriend in a totally Margo way. I wrote him a letter and left. That wasn't me, it was Margo."
