Prince Harry and Meghan Markle visit south London

Circulating social media, the cards feature the official Kensington Palace crest and feature a short note that reads: 'Prince Harry and Ms. Meghan Markle were incredibly touched that you took the trouble to write as you did in connection to their forthcoming Wedding.

The couple, set to marry May 19 at Windsor Castle, looked distinctly "loved up", as the British tabloids put it, dressed warmly and smiling warmly at well-wishers as they dropped in at a formerly underground radio station, Reprezent 107.3FM in Brixton, to see its program training youths in radio and broadcasting.

Their arrival was marked by an explosion of camera flashes from a large phalanx of photographers and TV cameras, as Markle, 36, smiled, waved, and blew a kiss to wellwishers outside Pop Brixton, a community project that houses independent local businesses, start-ups, new restaurants and the not-for-profit radio station in shipping containers. She recently moved from Toronto, where "Suits" is filmed, to London to live with Harry.

Twitter users were swift to identify her £45 sweater as from British brand M&S's Autograph collection, which Markle teamed with Burberry pants, a coat by Smythe, and a scarf from Jigsaw. "I can see why your show is so popular".

The bride's father, who has been divorced from Doria Ragland since Meghan was 6, has kept a low profile since the royal engagement was announced.

Miss Beyi said: "For two people who are making headlines in the news to come to a place where there's usually just a little column in the newspaper (about us) - I think a lot of people thought those two worlds would never collide".

The organisation's CEO Shane Carey welcomed the visit saying: "We're having the spotlight shone on us from all the world's media".

The couple is planning to Wednesday on May 19, 2018, at St. George's Chapel at Windsor Castle.
