The Hella Good singer dropped the divorce bombshell in August (15), announcing her near 13-year marriage to Bush frontman Gavin was over.

She subsequently poured her heart out in the lyrics and tearful video for her new single, Used to Love You, in which she sings about a love split, and she recently told U.S. breakfast show Today it was a "very real" reflection of her emotional state.

The mother-of-three has now revealed she didn't even want to head into the studio on the day she wrote the track because she was so heartbroken.

"On the way into the studio the first time, I didn't want to go," she tells U.S. radio host and The Voice presenter Carson Daly. "I wanted to be in my bed, like, crying. And I did, I cried all the way down to Santa Monica (in California), driving to Santa Monica, and I was like, 'What am I doing? Why am I doing this?'"

She eventually put pen to paper to describe her troubles in song, and once her creative juices started flowing, she couldn't stop.

"That feeling of being able to write again, that's everything to me," she says. "My value on myself is by songwriting... I think within eight weeks I had 19 songs... I was like, 'Listen all I wanna do is I just want to say the truth. I just want the truth to come out. I just want to be honest and real'."

In addition to her music, Gwen has also turned to partying to relieve her stress and she was spotted attending George Clooney's Halloween bash in Los Angeles on Friday (30Oct15) with her The Voice co-hosts Blake Shelton and Adam Levine.

The 46 year old admits her life has completely changed since parting ways with Gavin, but she has decided to embrace her new single status and just enjoy herself while she can.

"My life is so extreme right now," the singer continues. "My life basically blew up in my face. And now I'm in this new life, and it's pretty awesome I have to say - I'm so inspired being back on the show (The Voice), and just being in a new place. Everything just feels new. I just feel inspired. I don't know how else to describe it..."

"I was literally that party girl that you hear about when their life blows up, and you're like, 'Yeah! I'm going out! Like, watch me!' We're just trying to have fun, you know?"
