Molly Sims with husband Scott and son Brooks
Molly Sims is worried about how her son will react to a sibling.
The 'Carrie Diaries' actress, who is five months pregnant with her second child with husband Scott Stuber, also admits she has "weird thoughts" about not being able to love her unborn baby as much as their two-year-old son, Brooks.
She said: "I've already started worrying like, 'Oh my God, what's he gonna do when I'm in the hospital?' It's weird. Then you're like, can I love him as much as I love him or her? Those weird thoughts come, when you didn't even think two years ago you could love something this much."
The 41-year-old star hasn't told Brooks that he is going to become a big brother yet.
She told PEOPLE.com: "We're really not there yet, but I'm excited, I think we're gonna start to get a baby doll and bring it home and name it."
Molly's says her husband was "very shocked" when they found out she was pregnant again.
She said: "So he came home that night and I surprised him -- he was very shocked. And then I think I almost threw up on him, like, 'Here's the proof!' "
