The former sixth-grade teacher imprisoned for raping a student she later married wants to teach again.

Mary Kay Letourneau, now 53, and her husband Vili Fualaau, now 31, discussed their lives together with Barbara Walters in an interview airing on ABC News' "20/20" Friday night. Letourneau is a former suburban Seattle teacher who gained notoriety in the 1990s when she was convicted of raping the then-12-year-old Fualaau. They later married and have two teenage daughters.

Fualaau told Walters he has battled depression and would be upset if his children had a relationship with someone older, adding "I don't support younger kids being married or having a relationship with someone older."

ABC reported ( http://abcn.ws/1HaWnxr ) Letourneau is working as a legal assistant. She is trying to get her name removed from the sex-offender registry and wants to return to teaching.
