Secret ninja Katy Perry
'Waking Up in Vegas' singer Katy Perry says she is so good at disguising her appearance, no-one recognises her when she goes out in public
Katy Perry claims she is a ninja.
The 'I Kissed A Girl' singer - who is renowned for her outrageous outfits during her live performances - claims it's easy for her to remain anonymous as nobody expects her to dress down in public.
She said: "I am like a ninja when it comes to disguise. I am really good at putting on a hat and sunglasses and leaving my sparkly outfits at home and putting on some sweats or something."
Katy is now so good at fooling people, strangers have even started criticising her to her face.
She added: "A lot of people don't even know I'm in the same elevator as them. The other day I was at a show and there was this guy who said, 'Oh yeah, I hear she's a b***h but I wouldn't even know if she was in the elevator.' And I said, 'Yeah, me too.' "
