Katy Perry can't cook

Singer Katy Perry says that she is a bad cook and cannot even boil an egg, if required.

The "Roar" hitmaker also has some other negative habits like getting late for work and finding it tough to say no to sweets, reports femalefirst.co.uk.

"The first thing you should know about me is that I can't even boil an egg," said Perry.

"Secondly, I'm always late. I can't help it; I get it from my mother. Also I find it hard to turn down sweets if there are some in the studio," she added.

Meanwhile, Perry has for the first time posed with boyfriend John Mayer for the cover of their duet single "Who you love".
