Guess the beach bumGuess the beach bumSomeone's having some fun in the Hawaiian sun.

But just who owns this beach rump?

Step forward please Ms Nicky Hilton.

Nicky was snapped soaking up the sun in Maui, Hawaii with sis Paris, and seems the rest of the Hilton clan was there too.

And if you thought sandals, a sarong and sunnies were all you needed to tide you over in the wardrobe department while on a beach holiday, think again.

Because Paris has just added a new dimension to what's cool couture at the coast.

But is her look scorching, or scandalous?

Go and see our gallery of Paris and Nicky Hilton in Hawaii, and decide for yourself.
