Princess Diana was always lively and upbeat, even though British Royal Family protocol often calls for stuffy traditions and a ton of formality, the late People’s Princess loved to liven up Buckingham Palace, not just for her sake, but also for the sake of her boys –Prince William and Prince Harry. As a result, the Princess of Wales was known just as much for her humanitarian efforts and her epic fashion sense as she was for her lively and silly personality. Prince Harry recalled that his mother’s life motto was, “You can be as naughty as you want; just don’t get caught.”

Like anyone else in the ’80s and ’90s, Princess Diana adored the epic music of the era. She also counted some of her favorite artists like Freddie Mercury, Elton John, Michael Jackson and George Michael as some of her closest friends, but what was the princess’ favorite song?

Princess Diana’s favorite song was “Hello” by Lionel Richie

Like everyone else in the 1980’s Princess Diana was obsessed with Lionel Richie’s 1984 #1 hit, “Hello.” Back in 2015,  Prince William attended an event where Richie was performing. E! News reported that the singer told the crowd, “Many years ago I had the pleasure of meeting Princess Diana, and tonight we have Prince William here. I must tell you it is a pleasure to be with all of you but especially this gentleman, because his mother came to me…and she said, ‘My favorite song is ‘Hello.” So I thought, tonight the dedication is to you, my friend.”
