When Cowell asks why they didn't do something in Holland, the pair claim that they wanted to show the world what they can do.
Responding to their comments, Cowell says: "I've always said this, we always welcome everyone from around the world in this competition.
"I think we're very lucky to have you audition on this show because that's honestly one of the best things I've seen on this show."
