Once divine rulers of the land, members of the royal family were the original celebrities. Even now, some of Hollywood’s biggest names still get star-stuck when they encounter royalty, and a meeting with the Queen is considered to be an especially esteemed honour – one that requires A-listers to follow formal royal etiquette. (Even Madonna, a.k.a. “the queen of pop,” curtsied for the Her Majesty in 2002.)
Taylor Swift took things a step further in 2013 when the pop princess sang karaoke with Prince William during a charity event, in which the pair took the stage at the Winter Whites Gala to sing “Livin’ on a Prayer’ with Bon Jovi. Taylor later said she “loved meeting” the future King of England and called the once-in-a-lifetime experience "insane.”
Then, of course, there was the time when hip-hop’s royal couple, Jay Z and Beyoncé, “held court” at a Brooklyn Nets basketball game with William and Kate in 2014. The typically unfazed music duo seemed genuinely in awe of the royal pair as photographers eagerly snapped pictures of the famous foursome together.
