Ahead of hitting the road, the “Substance” singer spoke to ET about her excitement about getting back on stage.
"It feels so good to just be completely authentic in what makes me happy, to perform and sing, and I'm just really, really excited about it," Lovato told ET's Denny Directo. "I’m back to my roots and I’m no longer performing in little leotards and in stilettos, you know, trying to be someone I thought people wanted from me. Now I just get to be myself -- my genuine, authentic self -- and perform the songs that I want to perform."
