"Posting a #nophotoshop pic because I'm proud to show my body the way it naturally is.. (And there was great lighting...)"  Lovato has been adamant recently that she's shed any lingering insecurities that she's had about her body recently, continually flaunting her enviable body on Instagram to prove that she doesn't care how she looks. She echoed those sentiments in the "Allure" interview, too.  "I've never felt as confident in my skin as I do today," she explained. "A year ago, every inch of my body was covered by clothing and it was because I was hiding behind so many layers. Once I started to feel better about myself, I felt better about showing more skin."
