While on stage, they may rock the audience with their performances, but off stage, pop stars shock their organizers with the weirdest demands.

Cher?s needs include a television showing a classic movie channel but that?s not the weird part ? she also demands a special room backstage only for her wigs, reports The Sun . However, Christina Aguilera?s (photo) sternest tour demand has nothing to do with her accommodation backstage, instead it?s all to do with her trip from the airport to the stadium. Christina specifically demands a police escort for the journey. Moreover, when Jennifer Lopez planned to add her voice to a charity single to benefit AIDS victims, no one expected any diva demands. However, the singer demanded and reportedly got a white room stocked with white flowers, white curtains, white candles and white couches and a variety of complicated foods.

Soul legend Aretha Franklin also has a unique demand ? 25,000 dollars of her appearance fee must be presented to her in hard cash before the show. Not just that, Coldplay rockers seem to miss their family and friends so much that they demand eight stamped local postcards wherever they go.
