Mary Kay Letourneau, 43, married Vili Fualaau, now 22, in Woodinville, Washington, outside Seattle Friday.
Letourneau was released from prison in August after serving seven and a half years for raping a child. Fualaau was 13 -- and a student in Letourneau's class -- when the two began a sexual relationship.
She gave birth to their daughter shortly after her 1997 conviction.
She served six months and was released on probation, but was ordered to serve her full sentence after she and Fualaau were found together in a van, in violation of a no-contact order.
She gave birth to their second daughter while in prison.
