Demi Lovato thanks Gomez, Jonas for support

Singer-songwriter Demi Lovato has praised singers Selena Gomez and Nick Jonas for supporting her during her rehab stint.

The 20-year-old checked into a treatment facility to overcome her struggles with bulimia and self-harming in 2010. She has thanked her family and friends for helping her get through her darkest days, reports femalefirst.co.uk.

She said: "I ended up having to go through some stuff. Fortunately, I have family and friends around me who are very, very supportive of me and my recovery and everything I stand for."

"Nick especially. He's always been there for me. And Selena because she called me crying when I was in there and was just so worried. I was like, 'Look, I should be the one crying, it's all good!' But she was so worried and ever since then we've gotten closer," she added.

She also said she is feeling good about herself and insists she is doing much better now.

She said: "I have more confidence than I did a couple years ago. And to me, confidence is sexy."

The singer had previously claimed that rehab showed her who her real friends were.

She said: "A couple of months before I went to rehab, I had a birthday party, and there were a couple of hundred people there. It was full of people who I considered my closest friends."

"When I turned my phone on after being in rehab for three months, I expected lots of text messages and phone calls. I had four texts. That was a wake-up call," she added.

Lovato has cut most of her old friends out of her life.

She said: "I don't have loads of friends. I used to, but then I realised, do any of them actually care?"
