Madonna has been getting advice on her new film, 'W.E', from Britain's royal family.

The 'Celebration' singer has met with Britain's Prince Edward and Princess Michael Of Kent to ask them for information on King Edward VIII's romance with US divorcee Wallis Simpson so the movie is entirely accurate.

Madonna has also met with the Duke and Duchess of Gloucester, as well as Buckingham Palace staff and historians, to help her tell the story of how King Edward gave up the throne for Wallis in 1936, after a national outcry at their plans to marry.

A source told The Sun newspaper: "When the Palace was contacted by the film company for guidance on historical fact, they were a bit apprehensive at first given the subject.

"But when they heard Madonna was behind it they lent their support and arranged for key people to get involved."

"The entire Royal Family were contacted and asked if they would like to meet Madonna and production staff.

"Some senior figures turned it down. But others jumped at the chance."

The film will examine the relationship between Edward and Wallis, which was opposed by the British establishment and Prime Minister and led to Edward's abdication after less than a year as monarch.

Madonna's film - her second attempt at directing after 2008s 'Filth and Wisdom' - will also feature a modern romance between a married woman and a Russian security guard.
