Molly Sims is one busy mommy-to-be!

The Sports Illustrated swimsuit model looked fit and fabulous in stretch pants and a bright pink zip-up, as she struggled to juggle her bags around her baby bump, after picking up her pet Yorkie from the Vet's office, on Thursday afternoon.

Sims makes sure to keep her fans updated on the details of her pregnancy via, and she recently shared, "It's hard for even me to believe! The baby just started kicking and at this point it's only a matter of weeks until life as I know it is going to completely change – and I can't wait!"

The stunning supermodel has so far kept mum on the baby's sex, saying only, “He’s here. She’s here. We don’t know! Can you guess?”
