The 28-year-old former Hills star said "I do" to William Tell Saturday in an intimate ceremony along the coast of California in front of close friends and family, according to Us Weekly.
"What a perfect way to start our lives together; surrounded by the people we love most," the couple told the mag in a statement.
The former reality star had nine bridesmaids, one of whom was her Laguna Beach and Hills costar Lo Bosworth. They all wore dresses from Lauren's clothing line, Paper Crown.
Lauren and the 34-year-old lawyer met on Valentine's Day during a blind date set up by mutual friends in 2012. They later got engaged after William popped the question in October 2013.
"I am very excited to share with you guys that William and I got engaged over the weekend," she wrote on her blog. "I am beyond thrilled!" Lauren later gushed about William to Cosmopolitan, writing, "William hates it when I say this, but he really is a very nice guy, and when you meet a nice guy who also manages to keep your interest, that is the dream."
Congrats to the couple!
