The "Roar" singer has just announced the tour for her new 'Prism' album on her Twitter page.
Katy teased fans on Sunday night, saying, "Guess what...I'm going on a world wide tour! Playing all of your favorite songs and all the brand new ones...Guess where I'll be kicking it off?"
The only clue she offered was "I love these people and their accents."
This morning, we found out that she was referring to the UK, but she has promised fans that more dates will announced soon.
The other good news (still just for the UK people) is that Icona Pop will be joining her for Belfast, Newcastle, Nottingham, Birmingham, Glasgow, Manchester, Liverpool, Sheffield and London stops!
We can't wait until Katy comes to the US!
