Elsewhere in his set, Criss brought out Chasez — who is penning the musical to the upcoming Frankenstein musical, Playing with Fire — for a performance of two *NSYNC hits: “It’s Gonna Be Me” and “Bye Bye Bye.”
“I’ve known JC Chasez for a long time from my time in Los Angeles,” Criss tells PEOPLE. “I met him and we got on really well. We were writing music together and he’s just been such a bench in my life. I’ll ask him to show up for shows that I’ll play, if I’m doing ’90s songs, he’ll come up and say yes, which is beyond my wildest dreams.”
“I have to play it cool as if I think I belong singing his songs with him on stage,” Criss adds.” I was — I think people say this to be nice in interviews, like, ‘I was such a fan.’ But I was a f—ing fan! I am a f—ing fan of *NSYNC. I know that whole album like the back of my hand, No Strings Attached. And he was always one of my favorite singers so getting to be with him is pretty amazing.”
