London, Apr 22 : Hotel heiress Paris Hilton stripped down to tiny two-piece in a bid to promote denim jeans.

The 28-year-old socialite donned a bikini in a new ad campaign for fashion label Guess, famous for its designer denim.

She looked even more sizzling as she posed in another set of skimpy swimwear with her tiny chihuahua between her legs.

“Paris looked red-hot in her bikini but it seems like a funny way to sell jeans,” the Daily Star quoted an onlooker as saying.

"Guess do make other clothes but that still doesn’t explain her dog. Paris clearly believes less is more and thinks her body is the mutt’s nuts,” the witness added.

Hilton’s switch over to modelling comes after she boasted she was this generation’s “iconic blonde”.

She said: “There’s nobody in the world like me.

“I think every decade has an iconic blonde, like Marilyn Monroe or Princess Diana. And, right now, I’m that icon.” (ANI)
