Katy Perry has revealed she is hitting the road with a worldwide tour in 2014.
"I'M GOING ON A WORLD WIDE TOUR!!! Playing ALL your favorite songs AND all the brand new ones!" she tweeted.
She added: "#THEPRISMATICWORLDTOUR is coming May 2014! First stop: UK!"
Swedish pop act Icona Pop will support Katy on her UK dates.
Katy's fans, known as Kitty Kats, can get even closer to the singer with a special standing pit in front of the stage, called The Reflection Section.
Tickets for the tour will go on sale at 9am on November 22 from www.ticketmaster.co.uk.
Katy, whose new album Prism topped the UK charts when it was released in October, will release her new single Unconditionally on December 16.
