Katy and Kacey grace this week's Billboard Magazine and they share another thing in common, they've got a special coming to CMT on June 13th. Then later this summer, Kacey will be the opening act for Katy's Prismatic World Tour! In the article Katy says, "I think [Kacey] straddles the line like I straddle the line of appropriateness and still maintaining a sexuality that is healthy and exciting."


KATY STALKED KACEY. After she heard "Merry Go 'Round" Perry did a little bit of ol' fashioned cyberstalking -- "as I do with everyone," she notes -- and reached out to Musgraves about teaming up. The songs they worked on didn't make the cut on "Prism," but a partnership was born.


KATY HAS SEEN KACEY NAKED. "A couple times," Musgraves confirms. "And it won't be the last." They'll have plenty more chances for dressing-room exhibitionism when Kacey joins Katy's "Prismatic" tour in August.
