The couple wed in Santa Ynez, Calif, People reports, with a familiar face in attendance -- Conrad's BFF Lo Bosworth, also a former Laguna Beach star, was one of nine bridesmaids.
Tell popped the question last October, and the couple has been dating since Valentine's Day 2012, when they were set up on a blind date by mutual friends.
"I knew I was going to marry him; I just thought that it was going to come a little later," Conrad told Allure in March about Tell, who's also the former guitarist for rock band Something Corporate. "He picked the setting and did the ring all by himself, and I think he was really proud of it."
Conrad recently met up with her former Laguna Beach pals Stephen Colletti and Deiter Schmitz in August, when she was a bridesmaid at the wedding of her Paper Crown clothing brand partner Maura McManusin.
