Katy Perry’s “collaborating” with Sia

katy-perry-promo_thelavalizardKaty Perry’s been looking at Sia’s pubes and hopefully writing some songs with her too!

Earlier today the ‘Hackensack’ chanteuse tweeted: “Oh em gee @Siamusic just showed me her pubes. Yeah songwriting!”

“Yeah songwriting” indeed.

That’s it really.

Yes we're on bloody Spotify!
