Lady Antebellum -- featuring a heavily pregnant Hillary Scott, who is due to give birth next month -- brought their latest single 'Goodbye Town' to the stage at the 2013 CMT Awards (June 5).

The trio pulled double duty tonight, assisting Darius Rucker as his backup singers during his room-filling performance of 'Wagon Wheel.' When the threesome finally took the stage to perform their own song, the crowd was ready to narrow its focus on Lady A.

The band performed in the middle of the stage, with black and white footage and images of cars driving through small towns (which are reflective of the lyrics) unfolding on the video screens behind them.

It was a vivid and emotional performance, with Charles Kelley serving as the centerpiece and the force that drove the song. He pretty much sings lead on the song in the recorded version, with Scott backing him up. She couldn't move around too, too much, since she is about to pop, so it's probably a good thing that their new single isn't driven by her.

Regardless, the mom-to-be didn't miss a single beat, and her inimitable voice sounded as beautiful as ever. This is probably the last time we'll see Hillary Scott at an awards show before she welcomes her daughter. However, she will be making an appearance at the 2013 Taste of Country Festival, which runs June 13-15.
