Meghan and Kate's first post-wedding engagements
Harry and Meghan were back at work just three days after their wedding.

They had opted to delay their honeymoon to show their support for Harry's father.
Prince William and Kate, meanwhile, enjoyed a romantic break in the Seychelles after their spectacular wedding in London in April 2011. With their batteries recharged, the couple carried out their first post-nuptials engagement one month later in May 2011, welcoming the Obamas at Buckingham Palace.
