Former American Idol winner Underwood claimed that the country genre is suffering from PPTSD – Postpartum Taylor Swift Disorder. "People around the world are worried," she said.
"You can't turn on the TV or open up a newspaper, click on a website, without being reminded of the epidemic we're all facing," continued Paisley. "I don't think I'm out of line in saying that this condition has hit Nashville the hardest. Of course we're talking about PPTSD."
The pair went on to lament US president Barack Obama's lack of interest in the "Taylor Swift situation". "I'm pretty sure that's why the Democrats lost the Senate," Underwood joked.
"We're sad because it looks like New York's gain is Nashville, but country music's just gonna have to 'shake it off'," they sang tongue-in-cheek as the audience cheered.
Later on in the night, Miranda Lambert took home four awards and addressed Swift’s departure from country.
"She's a girl in her 20s living in New York so why not make a pop record? She's a phenomenon, an amazing talent," she said, before performing a duet with "All About That Bass" singer Meghan Trainor.
