Cara Delevingne is detailing her sobriety journey.

Six months after paparazzi photos of the model at Los Angeles' Van Nuys Airport sparked concern among fans, the model, 30, shared that she's sober and that she'd checked herself into rehab late last year.

"I hadn't slept. I was not okay," she told Vogue for its April cover story published March 8, recalling how the pictures were taken in September after she'd returned from Burning Man and was on her way to work. "It's heartbreaking because I thought I was having fun, but at some point it was like, Okay, I don't look well. You know, sometimes you need a reality check, so in a way those pictures were something to be grateful for."

In fact, the photos prompted Delevingne's friends to rush to her side.

"From September, I just needed support," she recalled during the January interview at her L.A. home. "I needed to start reaching out. And my old friends I've known since I was 13, they all came over and we started crying. They looked at me and said, 'You deserve a chance to have joy.'"

And the Carnival Row actress knew she was ready for a change. "I've had interventions of a sort, but I wasn't ready," she added. "That's the problem. If you're not face-first on the floor and ready to get up again, you won't. At that point. I really was."
