The interview: Britney Spears says she's met her "prince" after kissing a "bunch of frogs." And her fiance, dancer Kevin Federline, says he's "known for a while that she's the one."

In their first interview since their engagement, Spears, 22, and Federline, 26, gush to People senior editor Todd Gold about their whirlwind romance (they met in April), her five-carat diamond ring and their desire to have a big family (Spears wants four, maybe five kids).

Is she rushing into things? "This is my life and I don't care what people think," she tells People. "I'm going to get married. I'm in love."

Those rumors about a shotgun wedding? "I'm not pregnant," she says simply. Clearly, for Spears, love is the center of her life right now, perhaps even eclipsing her passion for music. The pop star, who in January had anulled a two-day marriage to a childhood friend, announced last week that she was engaged to Federline.

Between the kissing, the hugging, the "oh, baby's" and even some lap-nestling, the couple recount Spears' marriage proposal aboard a plane heading to New York after her European tour ended.

"We always talked about how some people don't have to get married when they're in love then all of a sudden I said, "what if you want to get married?" And I kind of went from there to asking him if he would marry me." Federline said no.

"I was taken by surprise. I thought the guy was supposed to ask the girl. So a couple minutes went by and then I asked her."

"My head was spinning," he says. "I'd known for a while that she's the one."

Spears: "Oh, baby. Really?"

Federline: "Yeah."(Kiss, kiss.)

The couple won't divulge any wedding details, but Spears says she checked the Internet to find a wedding planner to start plans immediately. She picked out her ring — a five-carat diamond, set on twin diamond-encrusted bands — about a week ago.

Spears has plenty of time to plan the big event. At least four months. That's how long Spears will be recovering from a June 8 knee injury, which meant she had to cancel the last leg of her Onyx Hotel tour. "I was ready for a break," she tells People. "It had been a great tour, but my head wasn't really into it." A greatest hits album is due Nov. 16.

Federline has met Spears' mother, Lynne, and gets her blessing. "They're a good fit," she tells People. And Spears has met Federline's parents. The pop princess is looking forward to meeting Federline's 2-year-old daughter with actress Shar Jackson, who is expecting a second child next month.

By the time he met Spears in April, Federline says, his relationship with Jackson "was already done. I love my children more than life itself. My kids will always be a part of my life." And it sounds as if kids will be part of the Spears/Federline family, too.

"I'm not going to say if it'll be soon," says Federline. "We're starting with a dog," adds Spears.
