"I am very excited to share with you guys that William and I got engaged over the weekend," the 27-year-old bestselling author wrote on Sunday, Oct. 13. "I am beyond thrilled! Get ready for lots more wedding content here on LaurenConrad.com as we begin the planning process." Alongside the caption, the blonde beauty showed off her stunning round-cut diamond ring. It will be the first marriage for both.
The Paper Crown fashion designer first started dating her 33-year-old Something Corporate rocker turned law student beau on Valentine's Day in 2012, and recently moved in together to her condominium in L.A.'s Westwood area.
"They are really excited they took this step," an insider revealed to Us Weekly in its Sept. 23 issue. "William knows he wants to marry Lauren."
The couple recently celebrated their year-and-a-half anniversary in mid-August. "Just looked at the calendar and realized it was a year and a half ago today that I met this guy...And I sure am glad I did," Conrad wrote via Twitter.
The former Hills reality star recently dished to Us how her now fiance fits right in to her family. "My family loves him, so they love when we come to visit," she revealed to Us at Downy's Pop-Up Laundromat event in NYC in early June. "We spend a lot of weekends there hanging out by the pool and doing nothing." When asked if a proposal was on the way she replied: "We aren't in a rush, though. We're happy where we are right now."
Conrad has previously dated former MTV costar Stephen Colletti, Brody Jenner, and actor Kyle Howard. She also dated Laguna Beach costar Jason Wahler, who just tied the knot with Ashley Slack this past weekend.
