Did Demi diss Kate Middleton?

Ever since Kate Middleton and Prince William got married in April 2011, the world has been watching for Kate to show signs of a baby bump. But when a magazine printed a photo of Kate with arrow pointing to her slender midsection, saying it was "expanding," Demi Lovato actually decided to stand up for the new royal. "Apparently Kate Middleton is pregnant because of this picture... Are you kidding me?!!" she tweeted. "And people wonder why girls/guys have body image issues. Whether she is or not, she still has a beautiful body." You tell 'em, Demi!
