Ever since she got out of prison on Aug. 4, after serving more than seven years for child rape, Mary Kay Letourneau has been trying to get her life back to normal. Staying with friends in Seattle, she has been going through old boxes of belongings, dodging paparazzi and trying to regain weight she lost behind bars. Normal for Letourneau, 42, also means rekindling her relationship with Vili Fualaau, now 21, who was 12 when she started having sex with him. A friend from prison, Christina Dress, says that, when asked, Letourneau replied, "Of course I'm seeing Vili." Says Dress: "If anyone thinks those two have not been intimate since her release, they are naive. They've been waiting for each other for seven years."

That may not be all they're up to. "She talked about getting married," says ABC's Barbara Walters, who interviewed Letourneau for a segment of 20/20 that will air Sept. 24. "It would surprise me if they didn't marry." The couple already have two daughters—Vili's mother has custody of Audrey, 7, and Alexis, 5—and a third child is a possibility. "If Vili wants a baby, she'll have a baby," says Dress, author of the recently published Mass with Mary: The Prison Years, cowritten with Letourneau. Whether Letourneau, who has registered as a Level 2 sex offender, will be able to placate all four of her kids with her ex-husband is another matter. Her oldest son, Steve Jr., 19, told Inside Edition he was still angry with his mother and doubts he will have anything to do with her if she stays with Fualaau. "I feel like we kind of missed out on a lot of stuff because of her," said Steve Jr., "because of the bad decision she made."
