Jennifer Aniston's ex-boyfriend John Mayer complimented Demi Lovato on his post in Twitter. com calling himself her biggest fan and that he couldn't get out her La La Land number from his mind calling it a "sophisticated" track. This has made Lovata gush. She told contactmusic. com, "That is quite possibly the best compliment I've received in this business.

Thank you so, so much!" That `tweet' prompted Mayer to respond, "You're going to make lots of records, I can tell. Write one song at a time and never, ever apologize for any of them, ever."

The teenager shot back, "That's exactly what I needed to hear today. If that's not inspiration, then I don't know what is." - Sampurn Media
