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.)
And by sheer star-wattage alone, such meet-and-greets often generate international headlines. In October, Angelina Jolie was made an honourary dame by the Queen and the event was deemed especially newsworthy, as it was Angelina’s first public appearance since her wedding to Brad Pitt.
While meeting HM Queen Elizabeth II involves a fair bit of pomp and circumstance, an encounter with the younger generation of royals tends to be less stuffy. When One Direction’s Harry Styles met the Duchess of Cambridge, he firmly shook Kate’s hand and congratulated her on her pregnancy.
“I said congratulations on the bump,” he told reporters. “She didn't look bumpy.”
Bandmate Liam Payne, however, did not feel so at ease. He later revealed: “It was the most nervous I think I've ever been in my life.”
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 last year. The typically unfazed music duo seemed genuinely in awe of the royal pair as photographers eagerly snapped pictures of the famous foursome together.
