Russian billionaire Roman Abramovich will be hosting what promises to be one of the most extravagant bashes anywhere to see in the new decade.

He and his girlfriend Daria Zhukova, are expected to spend up to $4.8m on a beach party for 250 people on the Caribbean resort island of Saint Barthélemy.

The London Times reports that the singer Prince is to perform for them for a fee said to be $760,000.

Kate Moss has reportedly joined hands with TV mogul Simon Cowell to launch 1-billion-dollar global entertainment company.

Apart from the two known celebrities, British businessman Sir Philip Green is also in the team.

The 35-year-old beauty will be directing the style and image of the brand, as well as giving fashion advice, and experts say if it is a success, she could double her fortune to $160 million.

The American Idol judge, Simon Cowell, who is known for his extravagant lifestyle, has recently got a personal tanning salon built in his 22 million dollar mansion so he can maintain the perfect bronzed appearance, the London Daily Mail reports.

Cowell, who is worth 188 million dollars, bought the property for $12 million nearly two years ago but razed the original structure to build his “dream home”.

Since then, Cowell has been busy renovating the two-storey mansion, and the most recent change in the mansion happens to be the installation of a solarium adjacent to the master bedroom with a full-length tanning machine and a smaller facial tanner.
