Simon Cowell's luxury X Factor tour bus

Simon Cowell travels to 'X Factor' auditions in a two-million-dollar tour bus.
The music mogul - who left the UK pop star search show to focus on setting up the US version - uses the 1,200 sq ft vehicle, which has two bedrooms and two bathrooms, to tour America for auditions .
According to RadarOnline, it also has a $150,000 mobile medical unit.
The vehicle - which also has a kitchen, green room and a huge cinema screen - costs $9,000 a week to run.
Simon is hoping the Fox show will wow viewers when it returns for a second series, after he replaced judges Paula Abdul and Nicole Scherzinger with Britney Spears and Demi Lovato.
Britney recently revealed she is having a ''lot of fun'' working with Demi, Simon and L.A. Reid and tries to be constructive in her advice for the auditionees.
She said in a new promo clip for the show: ''So far everything has been so fun for all of us.
''Everything is like a new experience for me, so it's a lot of fun and the talent has been amazing.
''I feel like my judging style is very subtle. I try to use constructive criticism.''
Despite saying she is ''subtle'', Britney - who has been described as an ''incredibly tough'' judge - is seen in the video dispensing some harsh words to one contestant.
She tells the hopeful: ''I wanna know who let you on stage.''
Meanwhile, fellow new judge Demi says she is a ''happy'' judge who values being honest to the contestants.
She said: ''The most fun about being on 'The X Factor' is seeing people that really wow you and knowing that you saw them before they were going to become stars. It really is an exciting feeling.
''I would say that I'm a happy judge. I'm really, really honest. That's the great thing about this panel - we're really honest.''
'The X Factor' will return to Fox on Thursday, September 13.
