Lauren Conrad is moving on to the next stage of her life: motherhood.

The former The Hills and Laguna Beach star announced Sunday on Instagram that she's expecting her first child with husband William Tell.

"Happy New Year! I have a feeling 2017 is going to be the best year yet," Conrad captioned a sonogram photo of the tiny baby.

Conrad, 30, is pregnant a little over two years after tying the knot with Tell in a beautiful wedding on the California coast.

Conrad and Tell, a 36-year-old graduate of the University of Southern California law school, wed in September 2014. They got engaged in October 2013 and began dating on Valentine's Day 2012.

However, the fashion designer laid eyes on Tell way before they sparked up a romance.

"I met my husband when I was 16 and sitting on stage at one of his concerts," Conrad recently wrote of Tell, who was in the band Something Corporate from 2001 to 2004, on her blog. "Ten years later, we were set up on a blind date."

Conrad left The Hills -- which MTV ended after six seasons in 2010 -- during its fifth season in 2009, ending a five-year period in which she starred on both The Hills and its Laguna Beach predecessor, which followed her as a 17-year-old high school senior in Laguna Beach, CA.
