Miranda Lambert opened up about being emotionally honest and vulnerable in her music, especially after her divorce with Blake Shelton. The 32-year-old singer, who recently released her single "Vice," said that she is "nervous as hell" about putting herself out there once again.

"I've been hunkered down for a year writing, recording, trying to live a normal life and getting ready for a new album," Lambert 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."

Lambert said that she has always been "pretty straightforward" when it comes to her music, and sees songwriting as "taking a journey with what’s been going on in my everyday life -- good, bad, ugly and everything in between."

In her latest song, Lambert talks about "heartbreak" and being "numb" and "lonely."

"Maybe I'm addicted to goodbyes," Lambert says in the track. "Sweet salvation on a dining room table / Waiting on me, where the numb meets the lonely / It's gone before it ever melts the ice... Another call / Another bed I shouldn't crawl / out of at 7 a.m. with shoes in my hand / Said I wouldn't do it, but I did it again / And I know I'll be back tomorrow night."

Describing the song, Lambert said that, "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."

Lambert and Shelton dated for six years before getting married. The two announced their divorce last July.

The singer told Billboard that it "takes a lot of confidence and strength to be willing to be vulnerable."

"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.

While the reason for the split was unknown, Lambert and Shelton were surrounded by several cheating rumors. Most recently, infidelity allegations resurfaced with OK! Magazine reporting that Lambert owned up to her friends that she was the real reason behind the breakup.

A source told the magazine that Lambert has been “wracked with guilt for a while” over her rumored infidelities, and “thinks that alcohol played a part in her behavior.” The source also said that Lambert “really wants Blake to know she’s sorry” and “doesn’t want to hold him back.” However, Gossip Cop debunked the report.

After Lambert and Shelton's split, the two moved on with their lives as the latter started dating Gwen Stefani while the "Little Red Wagon" singer got involved with Anderson East.
