Jerod Harris/WireImageLauren Conrad found true love.
The former Hills star and her boyfriend, USC law student (and onetime rock guitarist) William Tell, are getting married, the fashion designer announced on her website Sunday, and Conrad's inner circle knew all along that Tell was the guy for the blond beauty.
"They are perfect together," a Conrad source tells E! News. "Lauren loves that he is a normal nice guy who isn't really in the industry. She has never been this head over heels for someone she has been with."
Source adds that everyone close to Lauren knew William was "The One" the moment they met him.
"He loves her because she is sweet, beautiful and funny, to boot," source said.
Conrad tweeted earlier today, "Thank you guys for all the sweet messages! It means so much to me :-) Feel like the luckiest girl in the world!"
The 27-year-old wrote about the news and revealed her gorgeous ring on her website, telling readers, "I am very excited to share with you guys that William and I got engaged over the weekend. I am beyond thrilled! Get ready for lots more wedding content here on LaurenConrad.com as we begin the planning process."
The couple has been dating for nearly two years. Set up by mutual pals on Valentine's Day in 2012, the New York Times best-selling author fell head over heels for Tell, who, like Conrad, hailed from Orange County and was no stranger to show business, as he previously played guitar for pop punk band Something Corporate.
