The 27-year-old Lady Antebellum singer, who is nominated for Vocal Group of the Year with band members Dave Haywood and Charles Kelley, wore A Pea in the Pod midnight jersey dress that showed off her pregnant belly. The red carpet ensemble featured a beaded neckline and a low-cut neckline that played up her pregnancy curves.

A rep for Scott confirmed to Us Weekly in March that she and Tyrell, who wed in January 2012, are expecting a baby girl. The singer tweeted in January that she was putting her husband to work to help with her pregnancy cravings.

"Who has two thumbs and just asked her husband, and very nicely I might add, to run into the grocery store for pop tarts?" she tweeted. "ME! Pregnancy."
