A bishop from the US will deliver an address at Prince Harry and Meghan Markle's wedding.

Kensington Palace has confirmed that the Most Reverend Michael Bruce Curry, the 27th Presiding Bishop and Primate of the Episcopal Church, will be addressing the congregation at the upcoming nuptials at St. George's Chapel in Windsor Castle on May 19.

Bishop Curry said in a statement: ''The love that has brought and will bind Prince Harry and Ms Meghan Markle together has its source and origin in God, and is the key to life and happiness. And so we celebrate and pray for them today.''

Archbishop of Canterbury Justin Welby will preside over the exchange of vows whilst the Dean of Windsor will conduct the service itself.

Meanwhile, the Archbishop of Canterbury previously admitted he is listening to Stormzy to calm his nerves ahead of the upcoming royal wedding.

He said: ''I'm always nervous at weddings because it is such an important day for the couple - whoever they are. I've made a couple of cack-handed mistakes over the last couple of weddings I've been involved in and I'm thinking this is probably not a good moment to make it a hat-trick ... There's a line in that ['Blinded By Your Grace' that says - 'I stay prayed up and get the job done' - I think that sort of sums it up.''

And the archbishop is feeling the pressure at presiding over the wedding of the year, especially after dropping the bride's ring when his director of communications Ailsa Anderson wed journalist Simon Cole last September.

He joked: ''Unlike recent weddings, I must not drop the ring, and I must not forget to get the vows in the right order as I did at the rehearsal for one of my children's weddings!''
