ET caught up with Shawn Mendes ahead of his performance at the TIME 100 Gala in New York City on Tuesday, where he revealed he was too nervous to meet the members of the royal family.
The 19-year-old singer was recently in London, England, performing for Queen Elizabeth II's 92nd birthday.
"I stood next to the Queen for about 15 minutes, waiting to go on stage," Mendes told ET's Nischelle Turner. "We didn't technically meet, but I was standing next to her. It was really awesome! It was a lot more relaxed then I thought it would be, in the best way. That was just -- truly, I'm having a really great week."
"She's very funny," he continued."The whole royal family is very normal and just, like, super likeable and amazing."
Mendes said he also spotted Meghan Markle and Prince Harry, but didn't have the guts to talk to them!
"I didn't [meet them], I actually chickened out," he confessed. "I walked by the hallway and I saw them in there and I was like, 'Should I go say something? Nah.'"
"Usually I don't freak out like that, but I was really... I was surprised by how nervous I got in front of them," he added.
Although Mendes says he won't be at the actual royal wedding on May 19, he'll be watching "like everyone else."
