So how are she and her husband Jeremy Abrams faring so far?
"We are overjoyed, super happy and excited!" she tells the Dish. "We can't wait to meet the little peanut! I feel great so far and my belly bump is growing bigger every day, especially after a meal."
As for her cravings, Simmons reveals she hasn't had any out-of-the-ordinary ones. "I was craving a lot of peanut butter and jelly in the first few months," she says, "but the most constant craving I have is cold fresh fruit (watermelon, peaches, apples!)."
She's also taken a liking to cooling down with cold treats—especially while filming the show's latest season in the stifling New Orleans heat.
"Most of all, [I've liked eating] fruit flavored popsicles!" she says. "As summer has been so hot (and shooting in New Orleans was stifling), that is all I've wanted to eat."
