Meet Mary Kay Letourneau and Vili Fualaau's Teenage Daughters

What would the parents do if their daughters slept with a teacher?

They’re typical teenagers that wear high school cheerleader outfits and eat frozen yogurt and make funny faces at a camera.

But these are the daughters of the nation's most notorious school teacher -- the infamous Mary Kay Letourneau whose shocking affair with her student, Vili Fuaulaau, began when he was in sixth grade.

When the affair began, he was actually younger than his daughter’s current age.

Mary Kay is now 53, Vili is 31, and they're speaking out in an exclusive interview with Barbara Walters airing Friday night on ABC's 20/20.

Walters asked, “If one of your daughters came to you and said, ‘I’m sleeping with my teacher,’ what would you say?”

Vili laughed and replied, “What?! “I think it would be the same reaction any parent would have, you know, if their child came up and said, ‘I’m in love with my teacher.’”

Mary Kay then said, “What would you say if they were sleeping with anyone?”

Vili replied, “I don't know really how to deal with it.”

Believe it or not, they're about to celebrate their 10th wedding anniversary.

Mary Kay said, “I don't know if enough time will ever pass where it will take away what the media did to our story.  Because it was so big and they ran with it so fast.  There is a story of us that has a life of its own, but it’s not our story.”  

Over the years, INSIDE EDITION has followed the scandal as Mary Kay became pregnant with daughter Audrey and served seven years in prison for child rape.

And we were there as Vili saw his second daughter, Georgia, for the first time after Mary Kay gave birth to her behind bars.

Now the girls are all grown up today, 17-year-old Audrey graduates from high school in June and 16-year-old Georgia is a sophomore and sings in the school choir.  

They actually go to school in the same Seattle district where their mom used to teach and Barbara Walters says they're fully aware of their parents' notorious past.

Judging from the interview, the marriage has been rocky.  Vili says he suffers from depression and wasn't prepared for fatherhood at such a young age.

He said, “It was a huge change in my life, for sure. I don't feel like I had the right support or right help behind me.”
Walters asked, “From your family?”

He said, “From anyone. My friends couldn't help me because they had no idea what it was like to be a parent. We were all 14 and 15.”

INSIDE EDITION asked psychologist Jeff Gardere to watch the interview and give us his evaluation of one of America’s most scandalous couples.

He said, "It appears to have been their lifelong mission to show the world that it wasn't about a sex crime. It was about legitimate feelings that they had."
