Katy Perry's Veggie Fail

Despite Russell Brand trying to turn Katy vegetarian, she's apparently been secretly eating chicken on tour.

Katy Perry, who is currently on the US leg of her 'California Dreams' tour, has failed her challenge to go vegetarian like husband Russell.

Russ was crowned sexiest veggie last year by Peta, but Katy is too much of a meat lover to stick to his diet.

"Russell has been a veggie for 22 years, but Katy adores meat," a source told the Daily Mail.

"She did give it up for a while for Russell’s sake but is finding it a struggle."

Katy may not be loving the vegetarian lifestyle but she is loving candy floss, after tweeting this photo during her tour stop in Chicago.

"You can never have too much..." she posted with the picture.
