This past weekend, Demi Lovato was seen by a fan at Disneyland, and she was walking hand-in-hand with "some chick" (who has been identified as DJ Lauren Abedini.)
Not uncommon for friends to hold hands, so it doesn't mean Demi has a girlfriend.
Unless, of course, you factor in the booty grab...
Honestly, that's not even conclusive proof that either of those girls actually IS Demi. But even if it is, it's good to see a lot of people supporting Demi being happy, because at the end of the day, if she's dating a man, woman, or a pet rat -- if she's happy, everyone else should be happy for her.
