Actress and singer Demi Lovato took some time during her New Zealand concert on Saturday, April 25, to dedicate a song to Bruce Jenner following the athlete's 20/20 interview about his gender identity. Lovato joked during the introduction to her song "Warrior" that she didn't know who Jenner was prior to "Keeping Up With The Kardashians" -- and that her fans probably didn't either. "I want to dedicate it to someone who became an even bigger hero last night: Bruce Jenner," Lovato tells the crowd.
