NOW that's how you bling up a yacht.

A gold-plated super-yacht that is claimed to be worth a staggering £3 billion ($4.5 billion) has taken the title of the most expensive in the world.

UK designer Stuart Hughes claims that the 30-metre long History Supreme yacht is adorned with 100,000 kilograms of gold and platinum that covers more than half its surface and even comes with a statue made from the bone of a T-Rex dinosaur.

The base of the yacht as well as the deck, dining areas, rails and anchor are wrapped in solid gold and the sleeping areas are covered in platinum.

There is also a wall feature in the master bedroom that is made from meteoric stone and an aquarium made from 68kg of 24 carat gold.

Also on board is a luxury liquor bottle featuring an 18.5ct diamond, one of the world’s rarest.

Designed by jeweller Stuart Hughes, the “mammoth” project took over three years to complete.

The vessel even outshines Russian billionaire Roman Abramovich’s $450 million yacht Eclipse, which has its own missile defence system and a submarine.

It is claimed the History Supreme was completed in Malaysia two weeks ago for an anonymous businessman.

Mr Hughes has also produced laptops, beds, cars and a suit covered in precious metals.
