Lauren Conrad and her husband William Tell are proud new parents. The couple welcomed their baby boy Liam James on 5 July and decided to share the news with an adorable Instagram photo.

"He's here! We're so excited to welcome Liam James Tell into the world!" the 31-year-old new mother wrote alongside a cross-stitch depiction of her family with their new bundle of joy and two dogs.

"We are thrilled to share that we welcomed our son Liam James Tell into our family," the couple told People magazine "Mom, Dad and baby are doing well. We're already in love!"

The Laguna Beach alum told the entertainment publication that her two dogs are still getting used to baby Liam.

"Chloe and Fitz aren't so sure ..." she said of her pets' reaction.

This is Conrad and her entertainment lawyer husband's first child together since they got married in September 2014. Conrad shared regular updates on her pregnancy on Instagram starting with the announcement on New Year's Day when she posted a photo of a sonogram with the caption: "Happy New Year! I have a feeling 2017 is going to be the best year yet ..."

Speaking to People earlier this year, the fashion designer mentioned that she would be getting a lot of help taking care of the baby from both their families. "William and I are so fortunate that we're having the first grandchild on both sides," she said. "Both of our families live about 20 minutes from us so I think we'll have a lot of help, which is really great."
