Most likely a rumour spread by her ex Russel Brand but at some inside parties it is said Russel particularly liked her "bat-wings", i.e. she has large long pussy lips. Unfortunately they either don't show up here due to thick fabric or it is just that, a rumour, I'd like to think the former. Otherwise her large boobs are the only redeeming quality.
Russel Brand is into some kinky things which ultimately freaked Katy out. Apparently being Religious doesn't automatically make her freaky like some are, it occasionally happens.
Being religious she most likely only did anal to preserve her chastity.
However thanks for the crotch shots which are always welcome!
I have to laugh when I see a girl do this maneuver what other purpose can it serve other than to show it off.
