Molly Sims isn't shy about showing off her growing baby bump!

The 38-year-old supermodel, actress and TV host proudly displayed her growing tummy in a sheer leopard top while leaving a hair salon in Beverly Hills, Calif. Tuesday.

Sims, who married movie producer Scott Stuber in September, is 18 weeks along in her pregnancy. "No experience I've ever had compares to this little bun in the oven!" she recently blogged.

This will be the first child for Sims and Stuber, 42. According to the Project Accessory host, being pregnant isn't always easy.

"I've already been though the morning sickness (every morning from 4 to 6 a.m. for seven weeks -- it was the worst), the strange cravings (I'm looking at you, Kraft Easy Mac) and daily episodes of what I call 'pregnancy brain,'" Sims wrote. "But believe it or not, I'm cherishing every moment."
