Katy Perry has said she enjoyed hanging out “baller style” with the founder of Facebook, Mark Zuckerberg.

The pair came face to face when the singer visited the company's Californian offices yesterday (January 19) to announce the US leg of her California Dreams tour.

Perry posted a picture of them together on Twitter, and wrote: “Ya know just hangin' @ "the" facebook with "the" CEO. Baller style. I like him!”

She is the latest musician to visit the company.

Kanye West also previewed songs from recent album 'My Beautiful Dark Twisted Fantasy' when he met staff last year.

Meanwhile, Perry's California Dreams tour will feature 41 dates across the US and Canada.

The jaunt will also make two stops in the UK in spring and autumn.
