Mr Welby will officiate at the wedding of Prince Harry, 33, and Meghan, 36, in St George's Chapel at Windsor Castle.
But then again, a lot of people aren't surprised that Meghan Markle is fast becoming the most popular member of the British royal family.
Meghan will also make her first official appearance alongside Queen Elizabeth during Commonwealth Day at London's Westminster Abbey. And I bet most people confess that they'll find themselves glued to the TV when there's a royal wedding or something similar.
Prince William, who married Kate Middleton in 2011, also doesn't wearing a ring.
The Times quoted its source as saying the couple had been "doing wedding prep" with Welby.
According to a new report, a majority of Brits think that the American-born actress is so attractive that they already think she's the best looking person in the monarchy.
Couple set to Wednesday at Windsor Castle; wedding date presents potential scheduling conflict for Prince William.
She said: "The royal wedding is a chance for communities across the country to join together and celebrate this momentous and happy occasion for our royal family and for our nation".
After the carriage procession, a reception will be held at St. George's Hall, a state room in the castle. Her name is Parisa Fitz-Henley and the actress is slated to play Meghan Markle, the woman who stole the heart of the second son of the late Princess Diana, Prince Harry.
