"Growing Pains" star Kirk Cameron has a great love story. So great, he says he "can't [even] believe it's true."

In an interview with "Entertainment Tonight" on Thursday, the actor, who famously played Mike Seaver, recounted the first time he met his now-wife Chelsea Noble while visiting the set of "Full House." Cameron was there visiting little sister Candace, who played DJ on the show, and Noble was on set visiting a friend.

"It's a great story, I can't believe it's true. I came home and my mom said to me, 'Hey, when you were on the set today, do you remember that girl you met Chelsea Noble?' And I said, 'How could I forget -- she was beautiful and sweet and amazing.' And she said, 'Well she's even more beautiful on the inside than she is on the outside. She's been here for a few days and I just want you to know that if you ever meet a girl and you get married, I hope she's someone just like her.' And four years later, I married her."

Noble went on to play the role of Mike Seaver's girlfriend on "Growing Pains."

The couple -- who tied the knot in 1991 -- has six kids , including four adopted children and two biological children. Cameron has since become an evangelist and acts in and produces Christian-themed movies.
