And this is one of the best reasons!
In this hilarious clip from the film, Franco's character Dave Skylark is interviewing rapper Eminem.
During the interview, Eminem casually comes out
The Dark Horse singer actually loves Miley, but she's not a huge fan of her tongue!
In fact, Katy's in Australia at the moment and revealed on Live On Sunrise that when Miley went in for some spit swapping during her Bangerz show, she pulled away before they could tie tongues!
But we thought Katy kissed a girl and she liked it??! LOLz!
So why wouldn't the bubbly bopper be into a little more XXX-rated girl-on-girl action??!
Ch-ch-check out her sassy explanation and watch the rest of the super fun interview down under(above and below)!!!
