Blake Shelton wished he could have gone "into a coma" during his split from Miranda Lambert.

He said: "This time last year, there was no light at the end of the tunnel for me personally. There was a point there where I thought I didn't even want to exist anymore."

Blake underlined the extent of his emotional turmoil by revealing he spoke to people about going into a year-long coma.

He told People magazine: "I told people I wished I could go into a coma and wake up a year from now."

Blake's relationship with Gwen - who split from her husband Gavin Rossdale last year - took a romantic turn in November 2015 and the blonde beauty previously revealed they became close after he sent her part of a song he'd written and asked her to finish it.

She explained: "He had written this song and sent it to me on my phone. And he's like 'I wrote this song,' I was scared to listen to it like ... what if I don't like it? And I listened to it and I was like, 'Oh my god, I love this.'

"There was a time I was really insecure about writing. I went through such a drought where I was so insecure. I think when you have a really long career ... you start to compete with your own self and get insecure - like, I did that ... but how did I do that?

"With this song, he was like ... write the rest of it. And I was just like, 'OK.' Instead of being like, 'Oh, I don't know how to write, and what if he doesn't like it?' I just thought about what I felt and I just sent him back a verse that was basically to him. And then we had a song! We were like, 'Wow, we have a song together!' and that was it.

It's weird. It's natural."
