Congrats to Demi Lovato!

The 'X Factor' judge won the 2013 MuchMusic Video Award of the Year for Best International Video of the Year for her hit 'Heart Attack.'

Walking carefully to the podium in her sky high black pumps and matching mini dress, the newly blond starlet gushed, "This is amazing! It's so heavy!" she said lifting the dense black trophy. "I'm going to put it on my bookshelf ... I owe everything to my fans, my Lovatics -- you're everything to me, thank you so much!"
