Vanessa Minnillo's baby bump just made its red carpet debut!
The expecting star and husband Nick Lachey popped up today in Australia for the opening of Marquee at The Star in Sydney, Australia -- where she covered up her growing belly in a short white, flowy dress.
The duo was joined on the red carpet by Paris Hilton, Ashlee Simpson, Kellan Lutz, Joe Jonas, Mel B, Minka Kelly, Slash, Isabel Lucas and Wilmer Valderrama.
Worth noting that Minka is rumored to be dating Wilmer ... who is Ashlee's ex-boyfriend! Small world.
After the party ended, Nick and Vanessa retreated to their room -- where she tweeted a makeup-free photo of herself!
