On Tuesday, May 22, just three days after they tie the knot, Prince Harry and Meghan Markle will make their first appearance as a married couple in honor of Prince Charles’ 70th birthday. The garden party at Buckingham Palace, which honors Charles’ patronages, military affiliations and charities, will also pay tribute to first responders of the terrorist attack at Ariana Grande’s Manchester concert in May 2017. The palace already confirmed in a briefing earlier this month that Harry and Meghan will not jet off for a romantic honeymoon right after their nuptials on May 19. Instead, they are returning the favor and celebrating with Prince Charles just days after he throws an evening reception for the couple after they say “I do.” Yui Mok/PA Wire Matt Dunham - WPA Pool/Getty “The couple will be going on honeymoon, but not straightaway,” said Kensington Palace spokesman Jason Knauf. “They will have their first engagement as a married couple in the week after the wedding.” RELATED VIDEO: Meghan Markle’s Wax Figure Debuts at Madame Tussauds Harry, 33, and Meghan, 36, are reportedly planning a honeymoon in Africa, a continent that is special to them both.
