Princess Di's ex Hasnat Khan says new biopic portrays betrayal of their relationship

Princess Diana's former beau, Hasnat Khan, has slammed her new biopic 'Diana' claiming that the Naomi Watts starrer projects a betrayal of their relationship.

The Pakistan-born heart surgeon, who was nicknamed "Mr. Wonderful" by the Princess of Wales, said that he found it "very difficult" after she died in 1997 in a Paris car crash, the Daily Express reported.

The 54-year-old doctor added that only he and his closest friends knew what really went on in the couple's relationship.
