Katy Perry invites Prince William and Kate Middleton to her gig in Ottawa

Pop star Katy Perry tried to get the touring Prince William and Kate Middleton to attend one of her gigs. The Teenage Dream singer invited the Duke and Duchess of Cambridge, both 29, to her concert in Ottawa during their Canadian tour. Perry took to her Twitter page to suggest the pair should pop along to her show - and Kate should also bring her wedding dress along to the gig. But the royal couple were already in Quebec City by the time she posted her message last night. Katy, 26, wrote: "In Ottawa! Heard Prince William & Kate are here, come to the show!!! (Kate - bring the McQueen!) My opinion is that she is so lovely, for invite them to her show, but is a little bit vulgar to say: Bring the McQueen:P 


       I think royals need to calm down and relax sometimes O.o
