There's much more to Cara Delevingne than meets the eye. The 23-year-old British model stuns on the cover of Elle's magazine's September Issue, but it's her emotional side that shines through.

Inside the mag, Delevingne explains how yoga and Will Smith were instrumental in changing her life and career.

"For me, yoga's the only way I can really feel things and check how I am," said Delevingne. "Because there is always pain somewhere, even if it’s completely irrational pain, and it's always good to find it and get it out. If I don't cry pretty much every day I will hold it in, and it will manifest in me in things that are destructive, like my skin."

Last August, Delevingne opened up about her battle with depression. "All of a sudden I was hit with a massive wave of depression and anxiety and self-hatred, where the feelings were so painful that I would slam my head against a tree to try to knock myself out," she told Vogue magazine at the time.

When it comes to acting, Delevingne admitted to Elle that crying is the most challenging part of the gig.

"I don’t think I have ever, ever cried in front of more than one person ever, ever," she said. "Because I grew up in this very 'emotion is weak, head up, move on, onward and upward’ kind of way. Which is not healthy."

Luckily, Delevingne's Suicide Squad co-star helped her get comfortable tapping into certain emotions. Smith, a father of three whose eldest son is, Trey, is the same as she is, shared a parenting tool that really helped.

"Will Smith was telling me he brought up his kids to put their emotions first, and when I heard that, I was just like, 'Oh my God, that sounds like a fairy tale,' because emotions should be put first. It’s the most important thing," said Delevingne before adding, “No, I’m not going to start crying."

Delevingne doesn’t mind getting candid. She recently opened up about her 33-year-old musician girlfriend, St. Vincent, in British Vogue.
