Demi Lovato hotel nyc disney singer smile necklace

She sure knows how to get our attention with an in-your-face outfit!

Last night Demi Lovato greeted dozens of fans outside of her NYC hotel, and the 17-year-old starlet was wearing a very sparkly glam rock ensemble as she signed autographs and posed for pictures. But did she visit with boyfriend Joe Jonas later on? After all, he's staying at the same NYC hotel, and we wouldn't be surprised if the two Disney stars were enjoying a little room service together.
