LeAnn Rimes: America's Got Talent Performance TONIGHT!

A fresh faced LeAnn Rimes makes a quick phone call as she heads to pilates class on Wednesday (August 18) in Los Angeles.

The 27-year-old singer wore super short shorts and a Free City tank for her workout.

LeAnn had a busy day ahead of her – later in the afternoon, she went to rehearsals with her dancers before her performance on America’s Got Talent tonight!

Be sure to catch LeAnn at 9/8c on NBC!
