Once-forbidden lovers Mary Kay Letourneau (search) and her former sixth-grade student Vili Fualaau (search) sound like any soon-to-be newlyweds as they prepare for their nuptials.

The former Washington state teacher is already bubbling about her dress: "It's perfect for my body. It has just the right lines and is simple."

At 22, he's thinking more about what kind of work he'll need to support his ex-jailbird 42-year-old fiancée and their two kids: "Something in graphic designs, industrials, maybe design houses."

The pair spill their guts on segments of TV's "Entertainment Tonight" and "The Insider" starting Thursday. The shows will also document the couple's wedding, which will feature some of Letourneau's older kids.
