Whoa, mama! Carrie Underwood stepped out Wednesday evening at the CMT Music Awards in Nashville, Tennessee, looking sizzling in a white mini dress.

Underwood, 32, and husband Mike Fisher welcomed son Isaiah Michael in late February. Fisher accompanied his lovely wife to the event.

Underwood, who performed Wednesday night after changing into a black, floor-length gown, netted the awards for Video of the Year, Female Video of the Year and Collaborative Video of the Year with Miranda Lambert.

“Having a baby definitely changes your routine, and I have to work around his schedule,” Underwood recently spoke with People magazine of her regimen after welcoming Isaiah Michael. “Whenever he goes to sleep, I do the things I need to do for myself and make workouts happen when they can.”
