Madonna has reportedly banned husband Guy Ritchie from her bedroom while she's on her world tour - because he likes the air conditioning on.The Queen of Pop apparently decided the filmmaker would have to sleep in a different hotel room if he wanted the air con on at night - because she's terrified the cold air could affect her voice.A source is quoted in Britain's The People newspaper as saying: "Madge can't sleep with the air conditioning on because she gets too cold and it dries her throat out, which can lead to a husky voice."The 47-year-old - who is performing a string of sold-out dates across the globe - has banned air conditioning from her entire tour.Meanwhile, Madonna reportedly laughed "hysterically" after being told pop rival Mariah Carey had to cancel several tour dates due to poor ticket sales.The 'Hung Up' singer was said to have gleefully welcomed the news that Mariah had to shelve a host of US shows because of a lack of interest.A source told America's New York Daily News newspaper: "Madonna laughed hysterically. She has been asking her tour promoters to email her Mariah's sales."

However, Madonna's representative denied the two stars are feuding, saying: "She has no negative feelings toward Mariah."
