The Daily Mail reports that Mills had booked London�s Pineapple Dance Studios for the whole week, to undergo secret practice sessions with chorographers.
During the one day that Mills was in the studio, the publication claims Mills insisted the blinds were shut and staff on call at all times in case she needed anything. One insider told the newspaper: "They hadn't seen anything like it since Madonna filmed a music video there last year. She was quite demanding."
However, a spokesperson for Pineapple said that although Heather cancelled her booking, she did so before visiting the studio, and claims of her diva like behaviour were untrue: "A private studio was hired for Mrs. Mills-McCartney; however, the booking was subsequently cancelled within a contractually agreed notice period�Mrs. Mills-McCartney did not visit Pineapple Dance Studios at any time"
It�s unknown why Heather cancelled the rehearsals, but could have something to do with the divorce battle currently underway at the High Court, where Heather and Paul have been for the past two days.
Heather has also come under fire from disability campaign groups who were apparently unhappy that Mills was using her disabled parking badge when she�s taking part in a dancing show.
