She's no shrinking violet and just in case we didn't know it already, Katy Perry proves why in her latest video.

The saucy singer strips nude, wearing just a white wig and provocative pink headband, in California Gurls.

With a wink and a smile, the U.S. star is seen floating in a cloud in a Bruce Almighty-inspired pose. t is just one in a series of provocative guises Perry, 25, takes on in the video, which also features rapper Snoop Dog.

In another sequence she cheekily wears a bikini embellished with iced buns, apparently channelling 2003 film Calendar Girls, which sees a group of women pose provocatively with household goods.
