Heather Mills puts her best foot forward on Larry King

Heather Mills claims British Airways "humiliated her". The former model, the estranged wife of Sir Paul McCartney, lost her temper when staff used a wheelchair rather than a buggy to take her to her flight at London's Gatwick airport. According to Britain's Daily Mirror newspaper, Heather was over heard telling staff: "Have you got it in for me? This is vile! Why are you doing this to me? Don't you know I have only one leg? Why are you treating me like this?"The 38-year-old, who was flying to Brussels last week, had requested a wheelchair but had expected to be taken to her departure gate in an electric buggy. A source said: "Heather's face fell when she saw the wheelchair. She was mortified. She asked for an electric buggy but there was not one available."Eventually she decided to walk to the plane. Heather was clearly worried about how she would look being pushed in a wheelchair. A wheelchair was requested and provided. The fact she choose not to use it was up to her."British Airways has confirmed the incident took place. Heather's spokesman said she had been offered a wheelchair, which she declined, but denies there was a dispute.The former model was seen filming inside the London home she shared with Paul earlier this week. Heather headed to the $10 million St John's Wood mansion and spent two hours there, after meeting her divorce lawyers. She videoed the contents of every room before leaving with two suitcases filled with clothes.The footage is rumored to be for use during her upcoming divorce battle, but Heather's spokesperson insists she was filming the paparazzi following her.
