The 33-year-old star - who rose to fame as a glamour model - likes to be in the nude while enjoying the heat of the sun, and does so to make sure she does not get unsightly tan lines on her body.
Launching her new swimwear collection at The Works studio in London yesterday (07.03.12), she cheekily said: "I don`t go to naturist beaches or anything. I just like renting villas over the water and places where I can walk around with no clothes on and sunbathe completely naked all day. Don`t you wonder why I never have tan lines?"
Although Katie - who is believed to be back dating ex-boyfriend Leandro Penna - likes to get naked to sunbathe she prefers to dress up in the bedroom because it makes her feel "sexy".
She said: "I am obsessed with underwear, with stockings and suspenders, and so even when that is all taken off, I`ve still got something quite sexy on."
Katie and Leandro enjoyed a dinner date last week exactly 12 months on from the night they met at Sir Elton Johns` Oscars party in 2011.
Although they split up after a few months, they appear to be better than ever, with Leandro tweeting his love for Katie.
He wrote: "I love to feel the beating of your heart and the warmth of your body against mine two become one and the world is our oyster @MissKatiePrice (sic)"
