In a snap shared to Twitter by Pratt, Montag's growing baby bump is barely visible under her shirt as she flexes in the kitchen with her husband and some friends .
“Live más squad @tacobell @heidimontag @GrimmKardashian @BRANDONWARDELL," Pratt captioned the shot.
Montag also shared a photo from the day, tweeting an image of herself and Pratt.
“Thank you @tacobell for the Test Kitchen Throw-Down! Live Más,” she wrote.
At the kitchen, Montag and Pratt each created their own unique menu item, with Montag whipping up "The Trifecta."
“This is the best taco ever. It’s a triple taco!” Entertainment Tonight reports Montag as saying on the fast food chain’s Snapchat. “All the different Dorito flavors with a little bit of nacho cheese, bacon and supreme, who wouldn’t want this?”
Ultimately, Pratt's "Pizzarito," a pizza inside a burrito, was crowned the winner.
