"I like wearing things more fitted," the Fashion Star mentor explained to Us Weekly earlier this month. "You want to show off your bump! It's just so fun. You don't want to wear muumuus so you can moo around town."

Later on, she changed into a short leopard-print Dolce & Gabbana number with sky-high platforms to celebrate the launch of her Jessica Simpson Girls line at Dylan's Candy Bar.

"This is regular size. I don't think I’m going to fit into regular stuff for too much longer," she told Us at the event.
