Leona Lewis will strip off for animal rights charity PETA.

The X-Factor winner, 22, who went to Croydon's Brit School, follows in the footsteps of Streatham-born model Naomi Campbell and actress Eva Mendes.

She has been asked to pose for their "I'd rather go naked than wear fur" campaign.

A source close to Leona told The Sun: "She's hugely proud to have been asked. She's a strict vegetarian so it's a cause close to her heart."

The Bleeding Love singer refuses to wear leather and backs ethical designer Stella McCartney.
