Molly Sims is having a girl.

The pregnant model-actress took to her blog on Monday to reveal that she and her husband, producer Scott Stuber, are expecting a baby girl. Sims posted pictures of herself wearing a pink dress and carrying pink balloons.

"We couldn't be more excited," she wrote on her blog. "I can't wait to meet our baby girl and I just know that Brooks is going to be the very best big brother ever. Two kids under three...here we GO!"

In her blog, the "Las Vegas" star said she has been "much more relaxed with this pregnancy" than her first pregnancy. This will be the second child for Sims and her hubby, who are already parents to a 2-year-old son, Brooks Alan.

"To be honest, I'm incredibly excited, slightly scared and a tiny bit anxious all at the same time," she wrote. "As this is my second time around the block, there is no fear of the unknown. I also think because I spend a lot of my day chasing Brooks around, there isn't as much time to truly wrap my mind around the fact that our lives will be turned upside down (in a good way!) very shortly."

In September, Sims took to her blog to announce that she was expecting her second child with her hubby. At the time, Sims also shared a picture of her 2-year-old son Brooks sitting on her lap while she held signs that read "2 years" and "4 months."

Sims ended her blog writing, "We are over the moon and can't wait until our precious little girl arrives" and asked her fans what they thought the family should name their daughter.
