Prince Harry, Meghan Markle 3rd anniversary: Take a look at couple's heartwarming PDA moments over the years

It has been only three years since Prince Harry and Meghan Markle said 'I Do' and became husband and wife but feels like forever. The couple have gone through some massive changes in the public eye ever since they walked down the aisle and the biggest of it included stepping down as senior working members of the royal family. 

Today, the Duke and Duchess of Sussex are gearing up to welcome their second child -- a baby girl in a few weeks time and have settled in the US. On Meghan and Harry's third wedding anniversary, we decided to go back in time and take a look at some of their most heartwarming and affectionate moments during their public appearances.
