Lauren Conrad is officially a bride-to-be! The MTV star posted the news this weekend on her website, LaurenConrad.com, announcing that she and her boyfriend of almost two years, William Tell, are now engaged. The author included a picture of her new diamond, a large, several carat, round rock.

The 27-year-old designer and bestselling author first rose to fame when she appeared on the MTV reality series, Laguna Beach: The Real Orange County, while in high school. Laguna Beach later spawned The Hills, Conrad’s own show, which also aired on MTV.

After appearing on the famous music network for nearly six years, Conrad became a fashion designer, designing a line of apparel, shoes, and accessories to be sold exclusively at Kohl’s. She also published her first novel, L.A. Candy, in June of 2009; it hit the New York Times bestseller list immediately, and encouraged the young author to pen seven more young adult novels since the release of her first.

Tell, 33, is a law student at USC as well as musician and Cali native, just like his fiancée. He and Conrad began dating in early 2012 (Valentine’s Day, to be exact) and recently moved in together in Conrad’s apartment in L.A.

Conrad was, surprisingly, the first to break the news; she posted on her blog on Sunday, “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.”

We’re engaged! http://t.co/cmulMErNah 🙂

After receiving so much feedback, Conrad later added, “William and I are overwhelmed by all of your warm wishes. Thank you so much for sharing in this special moment.”

Conrad has made headlines in recent years for her choices in suitors; she previously dated actor Kyle Howard, as well as Kardashian brother Brody Jenner. During Laguna Beach and The Hills, Conrad was involved with costars Stephen Colletti and Jason Wahler; interestingly enough, Wahler got married just last weekend to girlfriend Ashley Stack.

No date for a wedding has yet been released.
