Country superstar Carrie Underwood is back and looking better than ever.

Carrie Underwood & Isaiah Tour Chatter

On Sunday, E! News posted photos of the "Little Toy Guns" singer when she attended the 2015 CMA Music Festival in Nashville over the weekend. She took down the house with a black top, jean shorts and a fancy beaded vest.

Less than four months after giving birth to her first child, she appeared pretty happy to be back on stage where her post-baby figure looked healthy and athletic.

Underwood became a mom in February when she gave birth to her son, Isaiah. The child's father is Underwood's husband, Mike Fisher.

She also posted a video of herself on her Instagram page singing "Little Toy Guns" at the CMA's where it definitely looked like an amazing night.

The singer told the site how she kept up with her exercise routines while she was pregnant even if it was something less extreme.

"While I was pregnant, I did everything I could to try and make smart choices," she said. "If I couldn't really 'work out' work out, I'd go walk and just try to stay active and after I had Isaiah, I couldn't work out for a few weeks 'cause I ended up having a Caesarean, blah blah, too much information."

Underwood added that sometimes she would change her diet around and do the best she could in her workouts.
