Molly Sims has revealed that she is expecting a son.

The 38-year-old is pregnant with her first child with husband Scott Stuber and can't wait for her bundle of joy to arrive.

Molly made the announcement on today's episode of The Talk and said she was only revealing the sex of her unborn because they are undecided on what to do with the baby's room.

"I'm going to make a little announcement," the model turned television presenter said.

"The only reason why I'm telling this is because we can't make a decision on the nursery. We are having a baby boy!

"I know Scott would have been so excited with a girl but he is such a sports freak he is so happy."

Molly has spoken previously about the unique concoctions she's consumed throughout her expectancy.

"[I love] Steak and frozen yogurt," Molly gushed to E! News. "[I eat] everything together".

Molly is reportedly due sometime in June. The couple tied the knot last September in a beautiful ceremony in Napa Valley, California in front of their family and friends.
