It's a boy!
"We are thrilled to share that we welcomed our son Liam James Tell into our family,” the couple told People of their 6 lbs., 14 oz. bundle of joy. “Mom, Dad, and baby are doing well. We’re already in love!”
She also shared the news on Instagram, captioning a needlework of the growing family, "He's here! We're so excited to welcome Liam James Tell into the world!"
Last month, Lauren revealed she was expecting a little boy on the social media platform.
"I found this adorable birth announcement while helping my Grandma move and I thought it was the perfect way to share that William and I are expecting a baby boy," she captioned a snap of an adorable vintage baby announcement.
The 31-year-old beauty shared a sunny poolside snap with her friends at her baby shower on Saturday, May 20 and she proudly had her baby bump on display in a blue-and-white striped maxi dress.
"So lucky to have these wonderful ladies in my life! They spoiled me with a beautiful shower today," she captioned the snap on her Instagram story, then shared a photo of her gorgeous cake topped with flowers and berries.
The former MTV star opened up about her pregnancy on her blog back in January and revealed her tips for approaching a mama-to-be.
Along with never asking a married couple when they are planning to have kids, Lauren, also pointed out that it is not a good idea to ask about the due date or comment on the size of the bump.
"While seeing a friend’s bump grow can be really exciting, you probably don’t comment on the size or shape of any other part of a woman’s body—and it’s not a good idea to comment on her bump either," she wrote. "Women carry their pregnancy in all different ways, and can be self-conscious about it. Whether a woman is bigger than average or she’s not showing as much as she thought she would be, keep in mind that it can be a very sensitive subject."
Lauren announced she was expecting her first child to kick off the new year.
"Happy New Year! I have a feeling 2017 is going to be the best year yet…," she captioned a perfectly filtered shot of her sonogram.
Congrats to the growing family!
