World, meet Molly Sims' adorable baby girl!

The model/actress revealed on Friday (March 27) that she and her family welcomed a gorgeous new addition into their little family, sharing a sweet photo of their newborn on Instagram.

"We welcome Scarlett May Stuber into our family," Sims captioned the "awww!"-worthy snap. "Our hearts are bigger with you here."

"On March 25th, 2015, Scott, Brooks and I welcomed a baby girl, Scarlett May Stuber, into the world!" she added on her official website. "Our little bundle of joy weighs in at 7.7 pounds and is 21 inches long. Momma and baby are doing well. We are thrilled that the newest addition has finally arrived and we are so excited that we are now a family of four!"

And we're so excited for them. Plus, how adorable is little Scarlett May in that white-and-pink starred blanket? We also have to admit we're kind of obsessed with her name. It's elegant and classy with just a hint of sass. (Maybe that's just because it reminds us a little bit of Scarlett O' Hara from Gone With the Wind.)

Sims married her husband, film producer Scott Stuber, in September 2011. A year later, they welcomed their first child, son Brooks, into the world. And now the happy fam is proud to be a unit of four. So cute!

Check out Molly Sims' sweeter-than-sweet baby girl in the photo above! Welcome to the world, Scarlett May — and congratulations Molly Sims and family on your newest addition!
