Carrie Underwood‘s stylist took the wheel on this one — and hit a home run.

The superstar, 32, stepped out on the red carpet for the first time since giving birth to son Isaiah Michael in February, looking radiant as she was warmly cheered by her peers and fans at the CMT Awards on Wednesday.

“Having a baby definitely changes your routine, and I have to work around his schedule,” Underwood recently told PEOPLE of her exercise regimen while shooting the fall campaign for her new fitness line, Calia.

“Whenever he goes to sleep, I do the things I need to do for myself and make workouts happen when they can.”

The “Good Girl” singer — who will perform her duet “Somethin’ Bad” alongside Miranda Lambert — wowed in a Thomas Wylde dress and Jimmy Choo shoes, paired with Kimberly McDonald jewels and a Deepa Gurnani clutch.

The musician chose an appropriate moment to make her new mama red carpet debut: She’s nominated for a total of five awards, including two for video of the year, two for female video of the year and collaborative video of the year.

Underwood announced her pregnancy last September with the help of their two beloved dogs, Ace and Penny.

And the proud country mama has been sharing adorable snapshots of her son ever since. In March, Underwood posted a sweet picture of her infant son clutching a little Nashville Predators hockey stick, a nod to his father, Mike Fisher, a forward for the NHL team.

More recently, Underwood captured an aww-inducing father-son moment of her two favorite guys snoozing while spending time with her in the studio.
