Model and actress Molly Sims welcomed her third child with her film producer husband of five years, Scott Stuber, on January 10, an adorable baby boy named Grey Douglas Stuber. The new addition to the Stuber-Sims family joins 4-year-old brother Brooks Alan and 1-year-old sister Scarlett May.

Sims took to Instagram today to announce the news and share the first photo of their tiny bundle of joy. "Welcome to the world Grey Douglas Stuber 1.10.17," she captioned a sweet snapshot of herself and the newborn. "Words do not express how grateful and happy we are to have another piece of magic added to our little tribe!"

The self-proclaimed “Hip Momma” announced her third pregnancy back in August with a heartfelt video. The actress got emotional on the platform, fighting back tears as she told fans “We’re having baby number three!”

We’re so excited for you, Molly!

In early November, Sims announced that she was having a boy by posting a photo of her baby bump covered in blue paint. “BOY oh BOY ... we're having a BOY!!!!” the expectant actress wrote.
