Las Vegas star Molly Sims is weeks away from motherhood and "so excited" to meet her baby boy. The model-actress says it's been a "good" pregnancy, but admits she feels like she's "exploding" now that the third trimester has hit.

The blonde beauty goes on to talk about narrowing down baby names ("I love Asher, Quinn, and Ford"), her top maternity fashion tips and welcoming her first child a little later in life with husband Scott Stuber: "I never thought I would have children young," she says.

How are you feeling? How's your pregnancy been going?

I'm good. Now that I'm in my third trimester, it's a whole new thing [laughs]! I feel like I'm exploding! I'm due in little over a month. It's been a good pregnancy, though. They say you're sick in the first trimester, you glow in the second, and you feel like an alien in the third. It's kind of true! You really start to feel big and uncomfortable, but it's so fun to be able to feel him—it's just the best feeling in the world.

Do you have any names picked out for your baby boy?

We do, but my husband wants to wait to meet him until we decide. I'm like, 'We're going to get stressed, let's decide.' So we had 'naming-baby day' the other day and—this sounds terrible—we narrowed it down to eight! We cannot make a decision! For my husband the name has to have three criteria: how will it sound over a loud speaker if they're announcing him at a sports arena, will he be made fun of in fifth grade, and does it have any meaning? Those are his three rules. I love Asher, Quinn and Ford—those are in my top eight.

How are you feeling about the upcoming birth?

I'm excited and nervous! We went for the hospital tour the other day which made it more real. We don't know what we're going to do at the birth: C-section or natural. We're just going to wait and see what he does. Right now it's just a waiting game. But a friend of ours had her baby on the way to the hospital, so I'm hoping that doesn't happen to me! But we're planning for a birth in the hospital and I'm hoping it won't be a C-section. I don't think anybody really wants a C-section—that's surgery, which scares me! But whatever has to happen is fine.
