"Clearly I believe in it because I've kept trying it," the actress says of finding her forever love in an upcoming episode of Oprah: Where Are They Now

After six marriages, actress Mel Harris, best known for her role as Hope Murdoch Steadman on the hit 1980s TV show thirtysomething, is still a believer.

“I’ve been married six times,” Harris, 60, says in an exclusive preview for Oprah: Where Are They Now? “It is what I am. Sometimes things work out, sometimes they don’t. Out of those I have two beautiful, wonderful children.”

Though the actress, who is costarring on Hulu’s drama series Shut Eye, has been around the block six times, her belief in a forever marriage is still stronger than ever.

“Clearly, I believe in marriage because I’ve kept trying it,” she says. “I’m married to a wonderful guy. I plan to be married to him forever and ever. I have a great life. I have lovely children. It has absolutely been the best — I’m going to cry — and the most rewarding thing I’ve done in my life. And the best blessing that anyone has ever given to me.”

Harris, who is currently married to Bob Brush — a screenwriter and television producer — has two birth children and two stepdaughters.

Oprah: Where Are They Now? airs Saturdays (10 p.m. ET) on OWN.
