Katy Perry has revealed that her husband, British comedian Russell Brand, sends "inappropriate" emails to her mother.

The singer, who married Brand last year, said her mum enjoyed the Arthur star's correspondence, even though she doesn't.

"He's very charming with my parents and he has an ongoing email love letter with my mum, and she loves it," Perry told OK! Magazine.

"It's totally inappropriate and I have to tell him to stop."

Perry also admitted that she had kissed a girl - the subject of her breakthrough 2008 hit, 'I Kissed A Girl'.

The singer is currently on her worldwide California Dreams tour in support of last year's 'Teenage Dream'.
