OMG, the perfect opportunity for Robyn to convert Katy Perry to feminism. It will probably go something like this:

Katy: Let's get drunk on the beach!

Robyn: Include me out.

Katy: Aw, really? I'll let my walls come down, down. We can dance until we die.

Robyn: Fine. But U know I basically run things like a dancehall queen, right?

Katy: Once U party with me you'll be falling in love.

Robyn: Ok, ok! I said U can hang with me.

[Six vodka redbulls later...]

Robyn: Stilettos and broken bottles. I'm spinning around in circles.

Katy: Gurl, there is totally sand in my stilettos! Samesies.

Robyn: My drinking's killing me. U know I am over 30, right?

Katy: Confesh: I kissed a girl just to try it. Hope my boyfriend don't mind it. [winks]

Robyn: I know ur bf is Russell Brand and all, but U know that is pretty offensive, right? Do we need 2 discuss self-determined sexual pleasure vs. sexual performance for the male gaze?

Katy: My head gets, like, sooooooo confused.

Robyn: U should know better. Also, U are, like, so pretty and strong, dancing on ur own.

Katy: So I am pretty without any makeup on?

Robyn: Gurl.

Then they go vibrator shopping together and collaborate on an album full of anthems about female power!!
