Vanessa Lachey's latest pregnancy craving is freezing cold!

The first-time mom to be, 31, and hubby Nick Lachey were spotted grabbing ice cream in Sydney, Australia Friday before hopping on a flight back to Los Angeles. While Vanessa satisfied her appetite with a double-scoop cone, Nick indulged both a cone and a cup of the frozen treat.

The couple, who wed in July, were down under to celebrate the opening of Marquee, The Star, Sydney. Making their first red carpet appearance together since announcing their happy news in the beginning of March, Vanessa showed off her bump in a short white chiffon dress while Nick, 37,looked dapper in an all-black suit.

At the soiree that took place Thursday, the pair were joined by celebs like Ashlee Simpson, Joe Jonas, Kellan Lutz, Wilmer Valderrama and Minka Kelly.

"G'day Mates!!! I'm loving Sydney, it's going to be sad to leave. Marquee Sydney, you know how to throw a party!" Vanessa posted to her Twitter account Friday.
