A former contestant on Britain's Got Talent and a gospel choir are among the performers who have been personally chosen by Britain's Prince Harry and Meghan Markle to play at their royal wedding next month.

Kensington Palace tweeted that the couple, who are due to wed in St George's Chapel in Windsor Castle on May 19, took "a great deal of interest and care in choosing the music for their service, which will include a number of well-known hymns and choral works."

Cellist Sheku Kanneh-Mason, who made it through to the Britain's Got Talent semi-finals in 2015 alongside his siblings The Kanneh-Masons, has been chosen as one of the musicians.

The 19-year-old was named BBC Young Musician 2016 and came to Prince Harry's attention last year when the royal saw him play at a charity event in London.

The Royal Academy of Music trained musician tweeted that he is "excited and honoured" to perform at the wedding, adding that he was "bowled over" when former Suits actress Markle rang him to ask if he would play during the ceremony.

The Christian gospel group Karen Gibson and The Kingdom Choir have also been chosen to perform at the upcoming nuptials. 

Gospel conductor Gibson said of the news: "The Kingdom Choir is truly honoured to be invited to sing at the wedding of Prince Harry and Ms. Markle, and very excited to be taking part in such a historic moment."

There will also be an orchestra conducted be Christopher Warren-Green who will be joined by Welsh soprano Elin Manahan Thomas.

Many Spice Girls fans had been eagerly awaiting a long-awaited reunion at the royal wedding after Mel B hinted that they would be performing at the reception but no news has been announced as yet.

Prince Harry and Meghan Markle announced their engagement in November and later revealed they would tie the knot at St George's Chapel at Windsor Castle on May 19, which will be televised live.

It's a busy time for the royal family at the moment, with Prince William and Kate Middleton welcoming their third child, a baby boy, on Monday.
