Molly Sims is expecting baby boy

Molly Sims is expecting a baby boy.

The 43-year-old actress and her husband Scott Stuber are set to welcome a little son into the world early next year and their other children Brooks, four, and Scarlett, 17 months, are thrilled.

Taking to her YouTube account on Tuesday (11.08.16), the blonde beauty uploaded a video of her lifting the lid on a box filled with blue balloons as she exclaimed: "We’re having a boy!"

Brooks added: "We’re going to have a baby brother."

And, although he’s still a few months away from meeting his little brother, Brooks has already chosen a name for his sibling.

Molly said: "Brooks is really excited to be having a baby boy. He’s already named it Jack and the Beanstalk-Batman. That’s his full name. It’s been really sweet to see him so involved."

And the trio aren’t the only ones excited about having another little boy toddling around the house, as Molly’s spouse Scott almost burst into tears when he was told he was having a son.

Molly explained: "When they first told my husband we were having a boy, I swear he almost started crying."

The couple – who got married in 2011 – have already picked out a few names they like, but are waiting until they meet the little bundle of joy next year to make their final decision.

She said: "I love Wesley and Finley and Dutch and Wilder."

Molly hasn’t had the easiest pregnancy so far as she’s been experiencing "crazy" sickness and can’t keep food down.

She said recently: "I’ve been crazy sick. I wake up in the morning, I feel like I wanna vomit. I have lunch and wanna vomit, and wanna vomit at dinner … and then when I go to bed, I still want to vomit. I have vomited at grocery stores, I have vomited in my house, I have gagged on my toothpaste."
