Paul McCartney's ex-wife, Heather Mills, is planning to take 40 friends on a £100,000 pound ($189,000) European birthday celebration. The Sunday Mirror reported on Mills' plans, which come after she revealed on television that she is not romantically involved with fitness guru Ben Amigoni. The Mirror reported that despite Mills saying she will never get married again, she and 22-year-old Amigoni were filmed suggestively in a training session for the TV show.Mills said she was not a gold digger, because most of her money goes to charities. Mills said the upcoming bash at a resort in Slovenia is her way of thanking her guests for their support through the divorce. However, the Mirror reported that some skeptics think the bash might be Mills' way of trying to win over some of the mutual friends she shared with McCartney.
