The X Factor judge stopped by Live! with Kelly and Michael this morning in NYC to sing her new single Heart Attack! And not only was she met with huge applause, her fans just couldn’t keep their wits about them — we’re talking some serious tears, people!
Ch-ch-check out her live performance (above)!!
Of course, it wouldn't have been a proper visit if Kelly Ripa and Michael Strahan hadn't asked about her judging gig alongside Simon Cowell. Demi said:
“I think I’ve lived a lot of life and I think I’ve kind of seen the world from a different perspective."
