Lovato is a longtime boxing fan, and said her favorite workout is actually jiu-jitsu.
“I've been a white belt for over a year now and so it's time [to get a blue belt]," she shared. "But I can't, you can't ask for it… It goes white, blue, purple, brown, black. So I'll have a blue belt probably by the end of the year. But we'll see what happens.”
