‘I don’t give a f*ck’: Demi Lovato lets fly during a revealing interview

As her fans and followers will know, Demi Lovato has endured more than her fair share of personal struggles, and after overcoming a drug and alcohol addiction the former Disney star has been eager to talk about the consequences of her troubled past.

Speaking to Complex magazine, the 23-year-old singer and actress admitted that her addictions meant she wasn't the easiest person to be around.

"Prior to getting sober, I was one of those people who was like, I don’t give a f*ck. Whatever. And I used that as an excuse to do whatever I wanted. I was a nightmare to work with," revealed the outspoken star.

The actress, who entered rehab in 2010, after a physical spat with a backing dancer has little good to say about the person she was back then, adding: "I was just bitchy, a c*nt."

Demi, who is also open about her bipolar diagnosis, recently took a stand against online trolls who purport to know her, saying: "Sometimes there's more shit going on than you see. Maybe you DON'T know every aspect of my life so maybe you shouldn't assume you know."

Props to Demi for her honesty.
