The 30-year-old former The Hills star announced the exciting news by sharing a photo of her sonogram on Instagram.
“Happy New Year! I have a feeling 2017 is going to be the best year yet…” Lauren captioned the post.
Lauren has been open about having kids and has said in the past that she waited to get pregnant after getting married so that she and William could enjoy their honeymoon phase. She tied the knot back in 2014.
