Molly Sims and husband Scott Stuber welcomed their second child Wednesday.
The 41-year-old model revealed the news Thursday on Instagram, writing, "We welcome Scarlett May Stuber into our family. Our hearts are bigger with you here."
Sims and Stuber are already parents to two-year-old son Brooks Alan. The couple married in September 2011, and announced the model's second pregnancy in September 2014.
"We couldn't be more excited," Sims captioned a photo of her baby bump on her blog in January. "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!"
Sims came to fame as a model and appeared in the Sports Illustrated Swimsuit Issue five times. She subsequently pursued a career in acting as Delinda Deline on NBC series Las Vegas, and last played Vicky/Mrs. Donovan on Sex and the City prequel The Carrie Diaries.
