London, April 16 : Heather Mills apparently got on the wrong side of the Miss USA pageant organizers with her unreasonable demands and her 'enormous ego.'

A source claimed that producers even threatened to drop her as a judge when she 'flat-out refused' to sign a deal allowing it to be shown worldwide.

"She wants to get paid if they resell the footage. Her ego is enormous," the Mirror quoted the source, as saying.

People who booked the 40-year-old former model for the show vowed never to work with her again, the source said.

"She treated this like she was starring in a big-budget movie," the source added.

The source further said that Mills even met with pageant owner Donald Trump to 'butter him up'.
