The trailer is 1,200 square feet and boasts two bedrooms, two bathrooms and costs a massive $9,000 a week. It also includes a cinema room with 100 inch screen, marble floors throughout, offices and an all-granite bathroom. It has 22 wheels and weighs in a whopping 30 tons and would cost $2 million to buy.

Simon Cowell’s trailer is not only huge but it is also extremely well equipped – boasting its own private medical centre that would put a hospital to shame.

The Lounge

Some 26 speakers adorn the walls of the trailer, which is manufactured by Florida-based Anderson Mobile Estates. All of the custom windows have full electric shades, which are controlled by AMX touch screens positioned throughout the space. The bar area flowers are changed once a week, in time for rehearsals on Sunday or Monday. Also pictured: one of three 60-plus-inch 3D TVs with a live feed to the X Factor studio.

All the walls and ceiling are super-soft Italian ultra leather, and the windows are treated with a solar tinted glass and Agron-filled thermal unit that reduce the A/C load by 23 percent.
 
The Second Floor

The upstairs of the massive structure allows Cowell to house multiple events at the same time. For privacy, he need only touch a button and a glass divider goes opaque.
 
The Makeup Area

Applying Cowell's light foundation only takes about five minutes, but if he gets bored during the process, he can press a button for a television set to pop out.
 
The Kitchen

Among the items Cowell keeps stocked: ginger tea, fresh fruit, crudite, Sierra Mist and, of course, plenty of Pepsi. Not pictured: the Sub-Zero refrigerator.
 
The Woodwork

From floor to ceiling, all of the wood in the trailer was refinished in Italy with 20 coats of hand-rubbed finish.
