Kelly Le Brock opens up in an exclusive interview with Closer Weekly about overcoming adversity and finding her purpose in life.

Despite shooting to fame in her first film, 1984’s The Woman in Red, the 57-year-old’s life has had its challenges – like the abusive behavior she had to endure while working as an actress and model in Hollywood, which she’s dealt with by working for the United Nations to help end violence against women. She also weathered a tumultuous ’90s divorce from her Hard to Kill co-star Steven Seagal.

“I decided to quit Hollywood to raise my babies away from the limelight,” she tells Closer Weekly. “I didn’t want them looking into any of the negative aspects of my divorce [from Steven]. So I ran for the hills, and I’ve basically been living in the wilderness [of Southern California] with no TV for 24 years!”

What’s seen her through the tough times, she says, has been her three kids with Steven: Annaliza, 30, Dominic, 27, and Arissa, 24, who co-stars with Kelly on Lifetime’s modeling reality show, Growing Up Supermodel, which debuted on Aug. 16.

“Becoming a mom gave me purpose, resilience and a reason to get up in the morning,” Kelly says. “And sexiness comes from experience, not being young, so I feel sexier than ever!”

So what made her come back to do a reality show? “Well, when you get to my age, you grow some balls,” she jokes. “When I was touted as a sex symbol and beautiful and blah, blah, blah, the irony is that I didn’t feel it. Now that I’m more mature and wrinkled — I actually do have wrinkles! — I’m much more comfortable in my skin. I’m happy with who I am and where I am.”

As for Kelly’s relationship with ex-husband Steven, she said there has been no progress there. “It’s been very sad, because it affects the children. But I’ve been married three times so far, and my attitude is “Never give up!”
