The Princess Diana biopic is getting plenty of buzz and criticism. Now, Diana's ex-lover Hasnat Khan says fans hoping to get the inside story on her life via the film, Diana, will be gravely disappointed.

Speaking with the U.K.'s Mail on Sunday about the movie, Khan said the movie got their romance "completely wrong' and denied claims that he had given the film his approval.

He also said that the movie's portrayal of his two-year romance with the Princess of Wales was inaccurate.

"I don't see this movie doing well at all. It is based on gossip and Diana's friends talking about a relationship that they didn't know much about, and some of my relatives who didn't know much about it either," he told the Daily Mail. "It is all based on hypotheses and gossip."

Diana, starring Naomi Watts and Naveen Andrews, is set to be released in September of this year, centers around Khan's romance with the Princess.

Khan, who hasn't seen the film, plans to keep it that way.

"A friend asked me the other day if I would sneak into a cinema to see the film. But there is no way I will watch it," Khan said. "There's no way I am going to go anywhere near it, not now or ever."

"Most of it is going to be based on gossip, and if I watched it I would be sitting there saying, 'That's wrong, that's wrong, that's not right' every second," he continued. "I couldn't put myself through that. It would be absolutely terrible."
