Mary Kay Letourneau (search) and her former sixth-grade pupil — the father of her two youngest children — will be married Friday night, "Entertainment Tonight" and "The Insider" reported Thursday.

Tents were being set up Thursday afternoon for the ceremony in a secluded spot in King County, according to the television programs, which obtained exclusive rights to cover the event.

A rehearsal dinner for bridesmaids, groomsmen and relatives was planned Thursday.

Letourneau, now 43, served 7 1/2 years in prison after she was convicted of raping Vili Fualaau (search), now 22. She was released last August.

The couple first met when he was in second grade. Their relationship became sexual when he was 12 and she was a 34-year-old married mother of four teaching at his elementary school.
