Lauren Conrad on Wedding Proposal: "I Had No Idea It Was Coming"

"The Hills" starlet graces the cover of January issue of Cosmopolitan magazine, where she talks about everything from her engagement to her body insecurities.

Lauren's fiance William Tell popped the question in October, but the blonde beauty was shocked by the timing of the proposal.

"I had no idea it was coming," Conrad told the mag. "I thought he would wait until he finished law school."

So, did he have any help picking out the ring?

"He didn't even ask my friends, which was a bold move," Lauren added. "He said, 'I know you, and I know what you like.' And I love it. It's perfect."

Well done, William!

Fans have been rooting for Lauren to find love for years, watching her ride relationship roller coasters with exes Stephen Colletti, Brody Jenner and Jason Wahler. So, how did she know that William is the one?

"William hates it when I say this, but he really is a very nice guy, and when you meet a nice guy who also manages to keep your interest, that is the dream," she continued. "If you're going to settle down, it should be with someone you can't stop thinking about. Especially if you're in your 20s. If I were single in my 60s, I would totally settle. I would!"

Even though Lauren is engaged, she still warns her fans to wait for the right person before rushing to the altar.

"You have the rest of your life to be married. Enjoy falling in love. When girls get caught up in the timeline, it becomes more about the wedding than the marriage. You should be with someone with whom you could elope this weekend and be happy."

While the fashion designer looks stunning in the magazine spread, she still has some insecurities about her body.

"I'm so jealous of people who completely love their bodies," Lauren said. "I think most women have trouble areas as well as areas that they like. So you play up your favorite parts and learn to dress around the others. I used to hate my legs, but now I always wear minis. It was an accident. In an effort to look taller, I started wearing really high heels with shorter skirts and ended up showing off my legs a lot."

We love LC's style and can't wait to see her wedding dress!
