Demi Lovato brought a whole lotta "heart" to 'Good Morning America' and the breakfast show's Summer Concert Series this morning (June 28). The singer performed her hit singles 'Give Your Heart a Break' and 'Heart Attack,' as well as her soon-to-be-hit 'Made in the USA.'

"I know it sounds cheesy, but I'm proud to be an American," she said about her new single before performing it, adding that it's about falling in love "in the best country EVER!" What a patriot our gal Demi is.

Lovato, who is currently dealing with the recent death of her father, was a consummate pro and seemed to be in a good mood during her 'GMA' stint. She was also asked about who has inspired her the most, to which she replied, "My mom has gone through so much and she's such a fighter, and if I can have half the strength she does, I'll make it."

Lovato performed 'Give Your Heart a Break' with the support of backup singers and dancers. With buttery blonde hair, and wearing a a denim vest over her white dress and cowboy boots, the singer stepped into a zone when she entered performance mode.

While she was a bit winded from waltzing across the outdoor stage on a hot and humid day, her smile was infectious and her voice was strong.

The depth and breadth of Lovato's voice was evident when she belted out her songs.

She's so adorbs, isn't she? We think she looks a bit like stunning actress Kate Winslet with her shoulder length, shaggy waves. Are we right, or are we right?
