Demi Lovato has written a new song that is "too personal" to share.

The 'Skyscraper' singer is proud of her latest studio creation but isn't ready to reveal the lyrics to her fans just yet.
He tweeted: "Wrote a new song.. Wish I could post the lyrics but they're too personal. Some day."
Demi - who recently split from boyfriend Wilmer Valderrama - recently admitted she felt she had something to prove to people when she returned from rehab in 2010 after undergoing treatment for alcohol and drug abuse, an eating disorder and self-harming.
She said: "I think people looked at me differently. I wanted to prove to people that I wasn't just a stereotypical Hollywood starlet who goes to rehab and falls back into the trap of the things that got her there. I wanted to make sure that the music that I made was great and that I was passionate about the music that I put out and I sang my heart out.
"And I also wanted to continue the message of using my platform for more things than just singing about heartbreak. That's what music is for, is getting you through times, but also using it to inspire people."
And although Demi is in a much better place now, the 23-year-old star insists going to rehab helped her to grow up "really fast".
She added: "For me, the transition was a little bit easier because I didn't have to do anything to break out of the Disney mould. It's a lot easier when you just go to rehab. So I kind of grew up really fast in the public eye in that way."
