Prince Harry turns crooner on stage for Hamilton musical appearance

MEGHAN Markle may have pulled focus when she and Harry visited a production of the hit musical Hamilton, but the prince stole the show when he got up on stage at the end of the night.

PRINCE Harry became the star of the show when he burst into song during an appearance at the hit musical Hamilton.

Dressed in a navy suit and tie the Duke of Sussex turned crooner offered a glimpse at his own performance while on stage with the cast.

The show was held to raise money for the Duke’s HIV education charity Sentebale.

“You say …” the prince started to croon a few words of the song You’ll Be Back, treating the cast and crowd to a song sung by the King George III character — the Duke’s sixth-great-grandfather.

The theatre then erupted in cheers and laughter.

“That’s enough — he did try, but I said no,” he said, gesturing to the show’s creator, Lin-Manuel Miranda, who stood behind him on stage. “I don’t know how these guys do it, every single night, and in this heat as well,” Harry continued.

The prince then went on to thank the crowd for their help in raising money to help children in southern Africa.

Mr Miranda later tweeted: “King George III’s great-great-great-great-great-great grandson The Duke of Sussex sang a few bars tonight #Hamilton LDN”.

"You say..."

The prince was joined by his wife Meghan Markle for the gala performance in central London.

While he wowed the crowed with his surprise vocals, all eyes were on her who wore a short, £320 ($A436) black Judith and Charles tuxedo dress and black high-heel shoes. The daring outfit was cut well above her knees and showed off her legs.

The Duchess of Sussex also ignored royal protocol by not wearing pantyhose. The Queen requires all royal women to wear nude stockings while in public.

It is not the first time Ms Markle has broken the rules, though. She has previously stepped out without stockings, exposed her shoulders and also broke royal protocol by giving autographs and taking selfies.
