"The last year of my life has been one of heartache and healing. Of learning to be honest. Accepting the flaws and celebrating the smiles," she began her caption. "Finding peace in dark places. Having some moments alone with me. Facing fears and feelings. All of them. I got to know my guitars. Became friends with a pencil and paper. Used melodies to lead me places I had never been. Made music with my friends. Because music is medicine. This means the world to me. Thank you for joining me on this journey."

She finished out the note with a pair of hashtags: "#vice" and "#musicismedicine."

"Vice" marks the Texas native's first new musical offering since she and ex-husband Blake Shelton divorced last summer. Wednesday will mark the one-year anniversary of the former couple announcing their split

Shelton has shared his side of the story in his recently-released album, If I'm Honest, which the 40-year-old has described as a "basically autobiographical" account of his experiences over the last year. 

Lambert's "Vice" will be featured on her forthcoming album, though few other details have been formally revealed about the project. Currently, Lambert is headlining her own Keeper of the Flame tour, while also joining Kenny Chesney for stadium dates on his Spread the Love tour.

She also seems to have found love again with singer Anderson East. The duo made their first red carpet appearance as a couple at the Academy of Country Music Awards in April, where Lambert told ET that she's "happy."

"I've been off the road a little bit, so I've been able to kind of go into the creative mode, which is good," she said at the time. "I'm not rushing trying to get a project done, just taking my time, enjoying it, going to see live music. Just kind of being in it. Just getting creative. That's what I do. That's what I love the most."
