Even though they're not together anymore, Britney Spears and Kevin Federline's whirlwind engagement—that began when she popped the question on her private plane—shouldn't be discounted for nostalgia's sake.
"It was about three weeks ago, and we were on an airplane to New York from Ireland," Spears told
People in 2004. (Trust us, we can't believe it's been 11 years either!). "I'd finished the European part of my tour and I was going home. I was ready to get back to the States. I was really happy. Kevin was with me, so I'd had a lot of fun on the tour. We were a couple hours into the flight, and we'd been talking the whole time, stuff about life, wanting to have kids, the future and everything like that. It was an intimate conversation. And we'd 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. I asked him... He said no because he thought it wasn't the right way to do it."
Her proposal made Kevin pretty surprised, but not surprised enough to ask her the same question minutes later.
"I said 'yes,' of course," Spears said.
