That's some sexy maternity wear!

A pregnant Adriana Lima made her baby bump debut Tuesday night in Miami, where she and her hubby, Serbian basketball player Marko Jaric, stepped out at the Brazil Foundation Gala.

The Victoria's Secret model showed off her famous long and lean legs in a loose sequined mini dress with a sexy sheer black hem and black peep-toe heels.

On March 20, the Brazilian beauty, 30, announced that she and Jaric, 33, were expecting their second child together. (They're already parents to daughter Valentina, 2.)

"Big news everyone! Marko and I are so happy to share some wonderful news with all of you! #ImPregnant," she shared via Twitter. "My favorite job in the world is being a mom! My family could not be more happy!"

The stunner shows off her flawless bikini body in the Victoria's Secret Swim 2012 catalog, out March 28.
