Happy anniversary to Lauren Conrad and William Tell!

The adorable couple celebrated one year of wedded bliss on Sunday. Conrad marked the occasion by sharing a short-but-sweet wedding video on Instagram, writing, "I can't believe it's been a whole year..."

Conrad, an MTV reality star-turned-lifestyle guru, tied the knot with her groom on Sept. 13, 2014 at a winery in Santa Ynez, California. The bride donned two dresses for the big day: one custom gown by Badgley Mischka Couture for the ceremony, and then a Monique Lhuillier gown for the reception.

"I don't know that I have ever been as happy as I was walking down that aisle," Conrad told Us Weekly last year of the wedding. "It was amazing!"

Tell, a University of Southern California law school graduate and a former member of the band Something Corporate, serenaded his new wife at the reception with a rendition of Frankie Valli's "Can't Take My Eyes Off You."

The happy couple first met when they were set up on a blind date on Valentine's Day 2012. Tell popped the question the following year in October 2013.

In August, Conrad wrote a blog post in which she addressed the best part of married life.

"My favorite thing about being married is knowing that I have a partner in life that I get to do so many wonderful things with," she wrote. "Dreaming of the things we will do 20 years from now is so fun."
