Katy Perry's announced the American leg of her Prismatic tour and for some of it she'll be joined by Tegan & Sara, which is nice.
The tour — which will also feature support from Kacey Musgraves and Capital Cities on certain dates — starts on June 22 and finishes on October 10.
Tegan & Sara don't join the tour until September so there's plenty of time for them to crack on with a new album (featuring collaborations with Max Martin ideally).
You can see the full list of dates as well as which support act is playing which shows right here.
