DWTS is an adult show? I don't think so. It's a family show if anything. Lot's of children watch it, so what is the big deal with having a 16 year old on it?
Like English pointed out, dancing lessons normally start at a very young age. The youngest age group for competitive ballroom dance is Pre-Teen I: 9 years and under. There doesn't appear to even be a minimum age to compete. Julianne Hough started dancing competitively when she was just 10. At the end of the day, its about telling a story through dance and song. I am just going to sit back and enjoy. Zendaya dances beautifully and Val has been at his creative best with the choreography so far.
