Demi Lovato was one of the highlights of last night's 2013 MuchMusic Video Awards, turning in two amazing performances during the show and taking home an award.
Watch Demi perform "Give Your Heart a Break" and "Heart Attack" in the videos--she's truly at the top of her game.
Demi tweeted during the show: "So honored to have won International Video of The Year!!! MY LOVATICS are the BEST!!! #MMVA Excited to perform soon!!"
As if that wasn't enough, Demi and Cher Lloyd also sang a duet of "Really Don't Care" at the B96 Pepsi Summer Bash in Chicago over the weekend...and they KILLED it.
