Keith Urban seems to be so in love with country music, that he wants to sing all the songs. Even the ones that aren't his. Could that be how he ended up backing Jillian Jacqueline -- with vocals and guitar -- on her new song "If I Were You"?

When I had the chance, I asked. And Jacqueline told CMT.com a little bit about how she managed to get Urban to collaborate with her.

“We had originally recorded the song as just my vocal and one electric guitar. Very stripped down," she said. "We sent it to Keith and he loved it and wanted to be a part of the song. So we took it to him and then it grew into something bigger from there.

"He invited me to his home studio while he recorded vocals and played guitar on it, and it all came together in a couple of hours. He sang his parts flawlessly along with my vocals while I was sitting next to him on the floor. It was the most laid-back and creative environment. We had a blast and he’s been super supportive of what (producer) Tofer Brown and I have done creatively with my music.”

And in a press release, Jacqueline expressed how much she loves the outcome.

“I couldn’t wait to share this song. I wrote it -- with Sarah Buxton and Jordan Reynolds -- about meeting and falling for someone new very soon after a heartbreak and feeling unprepared to love again,” Jacqueline said. Buxton has penned all kinds of country hits, including Urban's "Stupid Boy" in 2006 and his "Put You in a Song" in 2010.

When Jacqueline wrote this one, she said, it already very personal and bittersweet for a lot of reasons. And adding Urban just made it that much better. "The song was very real to me when I wrote it, and is now one of the most special songs of my career because Keith is part of it with me. His voice and guitar playing took this song to the next level," she said, "and I am so proud of it."

The song is the first look at her upcoming SIDE B EP.

Jacqueline will be on the road for the remainder of this year, opening for Florida Georgia Line, Maren Morris and Kip Moore. After that, who knows? Maybe she'll join Urban on tour in 2019.
