Prince Harry has met one of Barbados' most famous superstars, Rihanna, celebrating the nation's 50th years of independence. The singer was a surprise guest - for the Prince at least - at the annual Toast the Nation event celebrating national achievements. "Barbados remains a favoured holiday destination for British people, not only for the incredible natural beauty of your country but because you have a great warmth and generosity of spirit." Prince Harry said. Rihanna stood to greet the prince, who said: "Hello, it's very nice to meet you." The pair later sat side-by-side on stage at a celebratory concert.
