Katy Perry posts naked bath pic online

Katy Perry has posted a photograph of herself lying in the bath and eating pizza online.

The 'Waking Up In Vegas' singer uploaded the image to her Twitter account after claiming that a recent bout of the flu had left her craving her favourite foods.

"'Why is it that after not eating for three days all I can think of is food... food is smiling at me... luring me with sexual seduction," she wrote.

The picture was posted under the heading, 'I Have No Self Control'.

She later uploaded a digitally-altered photograph showing what she would look like if she ate her favourite foods all the time, joking: "More people are saying 'I'd still hit it' to the future me than the me now. Damn. Super size it!"
