Katy Perry's PRISMATIC TOUR is so hot right now

KATY Perry's upcoming Prismatic Tour is proving to be some of the hottest concert tickets of the year.

Last night the American pop star added a fourth Brisbane show, a fifth Sydney show and a seventh Melbourne show to the Australian leg of her world tour, which starts in Perth on November 7.

It comes less than 24 hours after a fourth Melbourne show and a third Brisbane show were announced yesterday morning because of such strong demand for pre-sale tickets.

The shows bring her Australian tour to 20 shows in total, meaning Perry will spend nearly two months in the country for the tour.

Yesterday Perry tweeted: "Let's just say, I AM FEELING THE LOVE!".

Tickets for the new shows are on sale now through Ticketek.
