Watch: 'I'm a world champion tap dancer'
A 15-year-old girl, who won gold while representing Great Britain at the World Tap Dance Championships, said it was a "mind-blowing" experience.
Mackenzie, from Leicestershire, won two gold, one silver and a bronze medal for group, formation and solo performances at the tournament which was held in Germany in September.
"The first day at the arena was just, kind of, mind-blowing seeing everyone there," said Mackenzie, who is part of dance group Tap Attack.
"It just felt amazing to do what I love to do. It means a lot to me to be able to go and show people my talent and what I can do."
