Kate Middleton cousin (PHOTOS and VIDEO) Playboy. Kate Middleton’s stripper cousin has stirred up even more unwanted press for Britain’s Royal Family.

Burlesque dancer Katrina Darling -- a second cousin of the Duchess of Cambridge -- appears on the cover of the September 2012 edition of the iconic men’s mag with eight pages of pictures inside.

In one spread, she strikes a sultry pose as she lies topless on a sheepskin rug.

The issue, which will arrive on newsstands Aug. 17, will also feature an eight-page pictorial of the royal relative.
