Vanessa Lachey is already giving into her pregnancy cravings!

Nick's pregnant wifey, looking fresh-faced and gorgeous without makeup, munched down on some White Cheddar Pirate's Booty popcorn while traveling back from Sydney, Australia where the couple celebrated the opening of Marquee at The Star. Who says expecting moms can't party?!

Enjoy all that pregnancy has to offer, Vanessa ... including those sweet treats!
