Margot Robbie mistakes Prince Harry for Ed Sheeran at housewarming party

"When I saw him I was like, 'Oh my God I didn't know Ed Sheeran was at the party!'" admits Margot Robbie when quizzed by Jimmy Fallon on her recent encounter with Prince Harry. The royal and movie star crossed paths in December when both attended a housewarming party for top model Suki Waterhouse. "You didn't know who Prince Harry was? He's the coolest!" quipped the Tonight Show host. "He wasn't wearing a crown though. I didn't know it was a prince!" the actress said in her defence.

This is the second time that Margot has talked about her hangout with Harry. During a press interview for her new film Whiskey Tango Foxtrot, in which she plays an investigative journalist, the stunning Australian star admitted that it took a while for her to realize that a party with friends quickly turned into an audience with royalty. "I didn't know it was him for about half an hour talking to him," she told Entertainment Tonight.

Jimmy showed the audience the star-filled photo booth picture.

Joining Prince Harry and Margot at the bash were Princess Eugenie, Cara Delevingne and actress Sienna Miller. Like all good parties, the A-list crew hit up the photo booth for some silly photos, one of which Jimmy showed the audience. The fun party picture was posted to Instagram on Dec. 27 but has since been removed.
