Katy's tour is coming and she kinda gave away most of the set list! Well, that's because all of her songs are hits! While on Australian TV promoting her tour she said, 

"There are going to be a lot of incredible visuals on this tour, and all the songs that you wanna hear.  'Cause I know for me, when I go see a show from, like, a big artist, I wanna sing the #1 hits: all of 'em.  So, any song that has...been a #1 or close to it, I'll be singing it."

The tour jumps off on June 22, and fans can already get their hands on exclusive jewelry from Claire's Boutique online now! And just check out one of her Instagram pics where she shares some sketches of the costumes!!
