In early March, the country star hinted at a possible breakup when she reflected on pouring her emotions into her music during a concert at the Thompson-Boling Arena in Knoxville, Tennessee.

“I make it my mission every single time I step on the stage that no matter what, no matter where I am, I want to make you feel everything you could possibly feel,” Lambert said before performing an acoustic version of her hit “Tin Man,” as reported by local news outlet Knox News.

“I want you to feel sad, mad, happy and nostalgic and really pissed sometimes. That’s my favorite. And part of feelings is also heartbreak, unfortunately,” she continued.

“But fortunately for me, I can use it for my art or whatever. I like to write sad songs. I like to listen to sad songs, so I want to sing y’all one,” Lambert concluded.

The duo first began dating in the fall of 2015 months after Lambert and ex-husband Blake Shelton announced their divorce that July.

The 53rd Academy of Country Music Awards are broadcast live from Las Vegas on CBS starting at 8 p.m. ET on Sunday.
