Rose Byrne Shows Off Her Baby Bump in a Chic Metallic Dress

It's only been a few weeks since the news broke that Rose Byrne was expecting her first child with boyfriend Bobby Cannavale, but the mother-to-be is already proving that she has great maternity style.

The duo stepped out last night for the Bring Change 2 Mind gala in New York City, where the actress showed off her growing baby bump in a sleeveless metallic Blumarine jersey gown. Byrne accessorized her dress with a gunmetal Oroton clutch and an assortment of Jennifer Meyer jewelry, styled her hair in loose waves, and added black nail polish to finish off her edgy look. Talk about gorgeous!

But this isn't the first outfit that has showcased the star's pregnant tummy—she was previously spotted in a chic plaid shirtdress at the airport and later in a cozy gray ensemble while hanging out with friends.
