Kelsea Ballerini has dropped her new collaboration with Carly Pearce and Kelly Clarkson. The song, “You’re Drunk, Go Home,” was Ballerini’s way to celebrate two of her closest girlfriends.

“I was looking at my friendships, because I love collaborating with friends,” Ballerini reveals on Apple Music Country’s Today’s Country Radio with Kelleigh Bannen. “My first call was Carly. And without even hearing it, she said yes, because we just go so far back and we just have so much respect for each other. And we’re sweatpants friends. That’s how I categorize it now. It’s very offline friends as well. And then, I texted Kelly Clarkson the song and she did vocals that night. I’m also just [like], ‘That’s why you’re a superstar.'”

The song is one of 15 songs on Ballerini’s new Subject to Change album, released on Friday, September 23. Adding her friends on “You’re Drunk, Go Home,” goes against everything Ballerini said she would, and would not, do for her fourth studio album, making a bold decision to change her own mind.

“I swore I was not going to have a collaboration on this record,” Ballerini reveals. “I said it in interviews, but I just wanted to step back and claim my space again and be like, ‘I want to make a record about me and I don’t need people to help me tell a story right now. I just want to tell my own story and just get back to the basics.’ And then, I wrote, ‘You’re Drunk, Go Home.’  … I loved the idea of having not one, but two, different voices, that have power and wit and sass.”

The idea for Subject to Change came to Ballerini before she even wrote the title track. As the Tennessee native navigated both professional and personal changes, including the end of her marriage to Morgan Evans  after five years, Ballerini wanted her new set of tunes to reflect all of the transitions and transformations she was experiencing.

“I knew that the record was going to be called ‘Subject to Change’ before I had the song,” says the singer. “I was listening through to the demos that I had collected over the year and a half of writing. And that’s kind of always my process. I listen through and let the songs tell me what the story is. Because I don’t ever want to write for a specific theme. I want to write about my life and then, see what the theme is.

“And the theme was change and evolution and growing up and a lot of contrast within that and juxtaposition within that,” she continues. “And I loved the idea that we’ve all been really challenged by change the last several years, and change that’s really out of our control, and change that’s kept us at home, and all of that stuff.”
