Reality show star and style queen Lauren Conrad is engaged.

The MTV personality and author, 27, saw her dating exploits and her friendships intensely chronicled on her many reality series ('The Hills,' 'Laguna Beach') on the network, which made her famous and a household name. She has finally found "the one."

LC, as she is affectionately known, will marry boyfriend William Tell, 33, formerly of rock band Something Corporate and now a law student. They have been dating since 2012 and live together in her L.A.-area condo. We'll skip the jokes about Tell, who shares his name with a historical folk hero.

Conrad has an eponymous fashion line at Kohl's in addition to her Paper Crown range, and although she hasn't been on an active MTV series in years, interest in her love life remains high in the media.

Conrad shared the good news via a blog post on her personal website, writing:

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 as we begin the planning process.

William and I are overwhelmed by all of your warm wishes. Thank you so much for sharing in this special moment :- )

Conrad's dating resume includes Stephen Colletti, Brody Jenner (of the Kardashian clan) and actor Kyle Howard. She also dated Jason Wahler, when both starred on reality TV together. He just married Ashley Slack this weekend. No, we don't think LC made her big announcement to one up him, either.

See the ring (and her pretty crimson mani) below. That's some rock.
