20. Prince William and Kate Middleton
Will and Kate, also known as Duke and Duchess Cambridge, are another famous couple. The two are adorable together, but they started as friends. They were friends for an entire year at St. Andrews before they began dating. The Prince did say that shortly after proposing Kate in 2010. They spent more time together laughing, having fun and discovering that they shared many interests.
In the present, they have three beautiful kids named Prince George, who is the oldest, Princess Charlotte, and Prince Louis, who is youngest. Above all else, the couple remains in love.
