Molly Sims is expecting baby number two with her husband producer Scott Stuber!

On Tuesday, September 30, the Las Vegas star made the big announcement on her personal website with a little help from her two-year-old son Brooks.

“I can’t even being to explain just how excited we are for a new baby,” Sims wrote. “We are so, so, so blessed as a family, and I’m speechless at the fact that we have the opportunity to bring a second bundle of joy into the world. As a new mom to Brooks, an entire world of motherhood opened to me along with a thousand and one questions.”

“I absolutely cannot wait to see what life will be like as a mother to a toddler and a newborn, and I really can’t wait to see Brooks as an older brother to Baby #2!,” she continued. “I just know that he’s going to be preciously protective. If it’s a girl, he’ll be her biggest supporter and confidant and if it’s a boy, I know they’ll be the best of friends, always getting into adventures together. Scott, Brooks and I can’t wait to welcome Baby #2 to the Sims-Stuber household!!”
