“If I Didn’t Love You,” a duet between Jason Aldean and Carrie Underwood, has tops the country charts this week. The song, written by Jason’s bandmates Kurt Allison and Tully Kennedy, along with John Morgan and Lydia Vaughan, was the first time the pair of superstars recorded a duet together. Carrie is really thrilled for the writers of the smash hit.

“The song was written by Kurt and Tully from Jason’s band and then John Morgan, who is like an artist/songwriter who Jason works with and then a new young songwriter, who’s very talented, named Lydia Vaughan. I’ve actually written with her kind of separately for other stuff and she’s super cool,” says Carrie. “So, they wrote this song and kind of what I love about the writers of the song is that two of them are in Jason’s band. They’ve known him for a long a time. They know his style, and then you have these two other artists and songwriters that that’s like they’re newer and this is kind of their first major write for them which is supercool that the song is doing so well for these young, these young’uns, to slide in there and have a really successful song right off the bat. So, I’m really excited for all of them.”

The duet is available now and can be found on Jason’s upcoming album, Macon, which will be available November 12th.

Carrie, who just released a special edition of her first Christmas album My Gift, is getting ready for her Las Vegas residency, Reflection, which begins December 1st at the Theatre at Resorts World Las Vegas.
