In a 2017 interview with The Guardian, Coyne said he first connected with Cyrus on Twitter in January 2014 after she sent him virtual birthday wishes.

"I tweeted her back my phone number and said: 'Text me.' Since then, we've texted each other every day," Coyne shared. "I'll say, 'What are you doing?', and she'll send me pictures of herself peeing."

"Sometimes it's 1,000 times a day, sometimes it's a couple of times a day, but we're in each other's lives," he added.

Cyrus recently posed topless for her January Rolling Stone cover story, in which she opened up about her sobriety journey and where she currently stands after having "fell off" during the coronavirus pandemic.

The "Prisoner" singer revealed in her interview that she was "back on five weeks" sober after drinking again while at home during the COVID-19 lockdowns.

While Cyrus admitted to the relapse with alcohol the artist also said she has continued to stay away from drugs.

"[I] haven't done drugs in years. Honestly, I never try to, again, be a fortune-teller. I try to not be naïve," she said. "Things f---ing happen. But from sitting here with you right now, I would say it would have to be a cold day in hell for me to relapse on drugs."
