Miley Cyrus has revealed that she has been sober for six months.

Speaking on Variety and iHeart's podcast, The Big Ticket, the 27-year-old explained that she originally got sober in preparation for vocal surgery, but decided to continue given that her family has a "history of addiction and mental health challenges."

"I've been sober sober for the past six months. At the beginning, it was just about this vocal surgery. But I had been thinking a lot about my mother. My mom was adopted, and I inherited some of the feelings she had, the abandonment feelings and wanting to prove that you're wanted and valuable," she said on the podcast.

"My dad's parents divorced when he was three, so my dad raised himself. I did a lot of family history, which has a lot of addiction and mental health challenges. So just going through that and asking, 'Why am I the way that I am?' By understanding the past, we understand the present and the future much more clearly. I think therapy is great," Cyrus continued.

"One of my favourite interviews is when I say, 'Anyone that smokes weed is a dummy.' That one I love to send to my parents, who are big stoners, every now and then. It's been really important for me over the last year living a sober lifestyle, because I really wanted to polish up my craft. I had really big vocal surgery in November. I had freaking four weeks where I wasn't allowed to talk. I was so ripped writing on the whiteboard, yelling at everybody. I had this one big bicep from just yelling at mom and still trying to do meetings. But it prepared me for the stillness and the quietness."

The Wrecking Ball singer then explained that she was initially concerned that people would think she was "no fun" given her new sober status, but conceded that the benefits to her lifestyle have been tremendous:

"It's really hard because especially being young, there's that stigma of 'you're no fun'. It's like, 'honey, you can call me a lot of things, but I know that I'm fun'. The thing that I love about it is waking up 100 per cent, 100 per cent of the time. I don't want to wake up feeling groggy. I want to wake up feeling ready."

Cyrus also opened up about her recent role as pop star, Ashley O, in Netflix's Black Mirror, explaining that she used upheaval in her personal life - when she and her ex-husband Liam Hemsworth lost their home in the Malibu fires - to help her tap into the role.

"It was just a really cool experience, being so isolated from my family and friends. I was able to really disconnect from myself, and I was really able to get into Ashley," she told the host.

"When Ashley wakes up from the coma and it's totally traumatic, that was the day that I had lost my house in Malibu to the fires. I was able to pull from that trauma and use that in the scene. There were times that I had to stop and just go outside and totally melt down. It was just a really interesting time for me because so much was falling apart in my personal life, and it was the same thing that was happening in Ashley's life. It gave me a lot to use."
