Jason Aldean has a lot to celebrate these days: He's up for multiple awards at the 2018 CMA Awards, including the evening's biggest honor, Entertainer of the Year. He's also about to be the proud papa to a new baby coming in February, as was well evidenced on the red carpet Wednesday evening (Nov. 14).

Aldean's wife, Brittany, is moving right along in her pregnancy with the couple's second child, and she showed her baby bump off beautifully with a sunny yellow gown that hugged her belly and showed off her curves. The strong color of the dress was an unusual choice, and a shade not often seen; it was perfectly offset by Aldean's own decision to go with an all-black ensemble.

Aldean's duet with Miranda Lambert, "Drowns the Whiskey," is up for three awards at the event. He himself will face off against Luke Bryan, Kenny Chesney, Chris Stapleton and Kenny Chesney for the night's top honor.

The 2018 CMA Awards are held at Nashville's Bridgestone Arena and aired live by ABC. The show is being hosted by Underwood and Brad Paisley, who have helmed the event for 11 consecutive years running.
