Demi Lovato has revealed that the two people who were genuinely there for her when she needed them the most were Kim Kardashian and fellow Disney starlet Selena Gomez. 

Speaking to Billboard.com about her ordeal, which saw her spend time in rehab for emotional issues and get diagnosed with bipolar disorder, the 'Skyscraper' singer explained that she discovered who her true friends really are:

"I feel like there are some people that you're friends with that talk to you on Twitter or you text, but the people that are really there for me, are the people that were there for me when I went into treatment."

"The people that were still calling me while I was in [treatment] was Kim Kardashian and Selena Gomez. Those two girls, they meant the world to me. They still do."
