Reality show star and fashion designer Lauren Conrad got the "best surprise ever" when her musician/law student boyfriend William Tell popped the question!
"I am very excited to share with you guys that William and I got engaged over the weekend. I am beyond thrilled!" the 27-year-old former The Hills star announced on her personal blog. "Get ready for lots more wedding content here on LaurenConrad.com as we begin the planning process."
Conrad -- who began dating the former guitarist for the alternative rock band Something Corporate in May 2012 -- also posted a photo of her stunning diamond engagement ring on Instagram.
"William and I are overwhelmed by all of your warm wishes. Thank you so much for sharing in this special moment," she added.
The engagement news ironically came along with the announcement that Conrad's former boyfriend Jason Wahler got married to model Ashley Slack on Saturday, Oct. 12, in Malibu.
