Katy Perry plans to ''fly around'' arenas during her upcoming Prism tour.

The 'Roar' singer, who put on a theatrical performance during the Grammy Awards last night (26.01.14), has teased plans for her eagerly-anticipated tour which kicks off on June 22 in Raleigh, North Carolina.

Speaking about preparation for the gigs on the Grammys red carpet, Katy told Entertainment Tonight: ''Every week we get together at my kitchen table and we kind of just go at it.

''What we're going to play, what we're going to look like, how we're going to fly around the arena.''

''It's going to be the most fun show you've seen. And that's saying a lot because I thought my last tour was pretty fun. Everybody left that tour being sprayed with confetti and whipped cream.''

The 29-year-old singer gave fans an idea of what the live shows will be like by performing her new song 'Dark Horse' dressed like a witch at the Grammy Awards at the Staples Center in Los Angeles.

She wore a black and purple dress and pole-danced against a broom stick before being surrounded by a ring of fire during the dramatic show.

Katy told E! News before the show that her performance was ''kind of inspired'' by Stevie Nicks.

She said: ''Let's just say, one of my favourite lines: 'Which witch is which?'''
