Katy Perry has stated she believes she's 'too old' to strip off into skimpy outfits.

Unlike fellow popstarsBritney Spears - who have all donned barely-there costumes for their latest music videos - K-Pez believes she's reached her stripping peak… at the ripe old age of 28.

Speaking to One Direction - who she infamously kissed on the cheek at last year's MTV VMAs.

The Roar singer confessed: "I’m really flattered, especially as there are a lot of younger ladies in pop music.

“I’d be a bit of a supermum — none of them are even 20 yet. I’ll be their Mrs Robinson.”
