Adele used booze to loosen up when she penned 21

During a recent chat with The Sun, Adele spoke about the role alcohol played in the creative process of her latest album.

"I used to have to lock myself away in my house, get pretty drunk and write a drunk diary - and that was the first time I could admit things to myself," she said.

"A drunk tongue is an honest one in my opinion and the next morning I would read it through with an awful hangover and, in the cold light of day, had to absorb my feelings about myself.

"I was a bit scared that I wouldn't be articulate enough."

Adele said in her younger years she had no regrets. As soon as she gained that sense of awareness, she found herself working with much more confronting material.

"When I was 18 or 19 I didn't regret anything, I was very much a teenager and thought I knew it all and that there was nothing else I could learn," she said.

"I started realising my own flaws and my disappointments and I started regretting a lot of stuff. It was quite an awakening."
