British royal Prince Harry cancelled an engagement during his trip to South America after falling ill. The fourth in line to the throne is currently in Chile and spent time with disabled children at the Fundacion Amigos de Jesus in Santiago over the weekend (28-29Jun14) when he showed off his dancing skills to Katy Perry's Firework. The Prince was an instant hit with the youngsters, but he had to sit out of subsequent motorbike lessons after coming down with a "splitting headache", with his spokesperson adding that Harry had been "feeling under the weather". He flew out of the country on Sunday (29Jun14). A post on the Clarence House Twitter.com page reads, "A huge thank you to the people of Chile for the fantastic welcome over the last three days. Hasta la vista! #HarryinChile."
