Molly Sims has revealed how her body is changing now that she is expecting her first baby.

The model turned television host announced that she and husband Scott Stuber were looking forward to welcoming their bundle of joy early this summer.

But the 38-year-old told Us Weekly at the Safe House premiere in New York that she has to wear strong undergarments now to smooth out her growing belly.

"I'm wearing Spanx! They're holding everything in," Molly exclaimed. "I have seen fat deposit in places that I have never seen! I broke down and went to A Pea in the Pod the other day I had to buy a new bra!"

The Project Accessory host revealed that she is still trying to stick to her healthy regime as much as she can.

"I'm still doing Tracy Anderson," she revealed of the popular exercise method. "Just not at the same high level that I was."

"I've definitely taken it down because you have to keep your heart rate between 140 and 150 so, it's hard, I'm not gonna lie."
