On Friday, the singer made a big announcement on Facebook about her upcoming world tour: Instead of having a musical warm-up act, Spencer West – a motivational speaker and activist who lost both of his legs at a young age – will greet her fans and tell them his story prior to her performance.
West and Lovato met in East Africa while they were both working with Free the Children, an organization that seeks to empower youth, and the pair became fast friends.
"Spencer West is not only a really great friend of mine, but a huge inspirational speaker," Lovato, 22, says in the video, which was posted on Facebook. "After I spent some time around him and realized what an amazing person he is and how incredible he is at speaking, I decided to bring him on tour."
