Ke$ha Says She & Tour Mate Pitbull Are “Incredibly Similar”

She's a glitter-obsessed female pop star.  He's a macho Latino rapper.  But  Ke$ha says her upcoming tour with Pitbull will be great because she thinks they're very much alike.

Speaking to MTV about their summer tour, Ke$ha explains that she's been wanting to do something with Pitbull for a while, since they first worked together back in 2009, when she guested on his song "Girls."

"The first time we met, we had a very cool thing happening, but I was like 'Aw, I'll never see him again.'  And then I kept on seeing him!" she tells MTV.  "And the more we saw each other, the more we got along, and I realized that actually, we're incredibly similar."

How so?  Ke$ha explains, "He just likes to have a good time and he's a super positive person, and I'm a really positive person who likes to get weird and wild."

So how will the tour unfold? Who'll open? Will they perform on stage together?  Ke$ha tells MTV, "How's it going to work? I have no idea! But is it going to be fun? Yeah. "
