Miranda Lambert recently released her first single since her divorce, and the country crooner is "nervous as hell" about putting herself out there once again with her new song, "Vice."

"I've been hunkered down for a year writing, recording, trying to live a normal life and getting ready for a new album," the 32-year-old singer told Billboard. "Now that I’m coming with a song, it does make me nervous, and I hope that people are respectful of it and understand what I’ve been doing."

According to Lambert, who split from fellow country star Blake Shelton last July after four years of marriage, she's always been "pretty straightforward" when it comes to her music. The singer said that she looks at songwriting as "taking a journey with what’s been going on in my everyday life -- good, bad, ugly and everything in between."

While many artists come back from a break-up with a fiery, bombastic single meant to put the past behind them, it seems as though Lambert is telling a different story about dealing with heartache at the bottom of a bottle, or, as she explains, "Vice" is a "a tear-in-your-beer song."

The singer admits that she's made a career on being bold and self-assured with her music, but argued that it "takes a lot of confidence and strength to be willing to be vulnerable."

Describing the song, Lambert lauded it's universal relatability, explaining, "Everybody has a vice. Everybody goes through a time in their life when they run to it a little bit more than when they don’t."

"When I’m journaling my life and putting it on paper to a melody and then allowing people to hear it, I can’t worry about what somebody might twist it into," she added. "Because it’s not like I’m hiding anything."

The "Little Red Wagon" singer said that every record she's ever made has been "a reflection of where I am right then in my life," adding that being emotionally honest and vulnerable in her new music "was never really a choice," given her high-profile divorce.

Back on July 19, one year after her divorce from Shelton, Lambert shared a message on Instagram, alongside a screenshot of "Vice" sitting at the top spot on iTunes.

"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. Finding peace in dark places," she wrote. "Music is medicine. This means the world to me. Thank you for joining me on this journey."

"Vice" is the first song off Lambert's currently-untitled fifth album, which she hopes to release sometime before Christmas.

While she seems to have made headway in the healing process, it's clear her divorce is still a sensitive subject for the country star. Last Friday, Lambert got teary-eyed while singing "Over You," the 2012 duet she co-wrote with her ex-husband, during her concert in Illinois.
