Pop Star Demi Lovato recently worked in BuzzFeed’s New York offices for the day and penned a few posts for the news and lifestyle Web site. The “X Factor” judge’s writings included an article called, “Signs You’re Turning Into Demi Lovato,” and such hints as: “You like to post embarrassing photos of your friends and colleagues;” “You’re really not into taking selfies for the entire world to see;” and, “You’re not particularly attracted to either Ryan Gosling or Channing Tatum.”
