Demi Lovato

Actor Wilmer Valderrama has praised ex girlfriend Demi Lovato. The NCIS star showed his support for his 25-year-old ex after she performed her song Skyscraper at a March For Our Lives rally in Washington DC over the weekend. "She's a hero. She's a hero to young men and women out there. I think that she's literally the image of recovery and getting their life together, so I'm excited that she's there and for this historic moment for young people too," Valderrama told Entertainment Tonight.
