"When you're wearing real maternity, you're like ahhhhh! It's so comfortable… it does make a difference,” Sims said.
Molly is pregnant with her second child, a girl due any day now with husband and producer Scott Stuber, with whom she also shares her 2-year-old son Brooks.
So what's Molly been craving this pregnancy? Before our correspondent Terri Seymour delivered her baby girl on March 9, she sat with Molly to chat "mommy-hood"… and it turns out Molly's been all about the birthday cake this pregnancy.
"I picked up a birthday cake the other day. I was eating it in the car with a plastic fork like shoveling it in… I'm like, clearly you are pregnant."
Molly also told Terri she feels so much more empowered the second time around, considering she was so worried about becoming a mom when she was pregnant with Brooks.
Sims explained, "I was so worried about like breast feeding and it didn't come natural and I had no milk and he was born with a tooth and then."
"He was born with a tooth? Ouch!” said Seymour.
"It was so fun, let me tell you,” Molly joked, “But I love being pregnant this time. I've embraced it. I'm wearing amazing things."
