Katy Perry flashes naked booty to the world

The 32-year-old American singer Katheryn Elizabeth Hudson a.k.a Katy Perry is living in a Big Brother style house and having her every move filmed as part of a live stream on YouTube to promote her new album, Witness.

Katy is really giving fans a good look at her true self  as she flashed her bum to the whole world in more ways than one And by every move, we mean even those that leave Katy exposed.


The Swish Swish singer accidentally bared her naked booty while lying down for a massage.

Katy was visited by osteopath to the stars Vicky Vlachonis, and lay nude under a blanket as she prepared for her treatment.

However, as she adjusted herself, the towel slipped and exposed Katy's backside – although she should count herself lucky she didn't show off anything more intimate.

Katy has been very complimentary about Vlachonis in the past, counting her as one of the ten women who have changed her life.

She told Glamour: "Vicky has taught me that what you put in your body connects to your emotions. She helps me find my centre again."

Elsewhere on the live stream, the popstar has been treating fans to live broadcasts of chats with celebs including America Ferrera, RuPaul and Anna Kendrick.

However, the most candid chat came with James Corden, as Katy was challenged to rate her ex-boyfriends' sexual prowess.

After being dared to eat an old egg or chart Orlando Bloom, John Mayer and Diplo in their performance, Katy decided that John was the best in the sack.

It is believed this live stream will culminate in a special performance from Miss Perry, who has released three singles from Witness so far.
