CURVY Kelly Brook is to go naked for legendary men's mag Playboy.
The 34E Brit model and actress will pocket $500,000 - £340,000 - when she strips for "arty" pictures later this month.
Kelly, 30, will be photographed by an A-list snapper on a two-day shoot in the Mediterranean.
A source told The Sun: "This is a huge opportunity for Kelly who is without doubt one of the world's most beautiful women.
"Playboy is an iconic publication which is known across the world as a sophisticated title. Kelly can't wait as they are promising a very arty shoot.
"It's a real honour to be asked to do Playboy as obviously they are very picky about who they want.
"And by the same token it's a real coup for Playboy as there probably isn't a red-blooded male who won't be looking forward to the pictures."
Kelly - dating rugby star Danny Cipriani, 22 - will appear in the US-based mag in September or October. It was set up in 1953 by Hugh Hefner, now 84, and featured Marilyn Monroe on the cover.
Since then stars going nude for it have included actresses Pamela Anderson, Drew Barrymore and Kim Basinger, singers Belinda Carlisle and Dannii Minogue as well as former Page 3 girl Sam Fox.
Kelly has already peeled off for new horror movie Piranha 3D - in which nubile women are attacked by monstrous deadly fish.
