It has been 18 years since Princess Diana's death, but various conspiracy theories surrounding her accident may still be far from being laid to rest.

Just like the conspiracy theory highlighted by the cover of Globe Magazine's recent issue. The magazine was headlined, "Never before seen last photo reveals... Diana Autopsy Cover Up!"

The cover showed a black and white photo of a woman with similar features to Prince Charles' late wife who appears to be rescued.

The magazine cover went on to tease, "She was still alive in car wreck!" and "World Exclusive, Secret CIA crash file exposes murder proof!".

Other juicy teasers about conspiracy speculations surrounding Princess Diana's death also included "Charles ordered evidence destroyed!" "Princess was pregnant!" and "What docs did to her body".

Various conspiracy theories about Princess Diana's untimely death involve Prince Charles. The report released by Globe Magazine is no different.

"A popular theory among Princess Diana's devoted followers was that her husband Prince Charles and the royal family ordered to have her murdered and covered up her death," Celeb Dirty Laundry reported.

"Supposedly, Princess Diana was pregnant with her lover Dodi's baby - and the royals didn't want her to bring shame on their family by giving birth to someone outside of their bloodline," the report continued.

It has been widely rumored in the past that Prince Charles was allegedly in love with Camilla Parker Bowles even when he got married to Princess Diana.

A royal family insider previously revealed that the "People's Princess" allegedly tried to get out of the wedding at the last minute, but she was purportedly not allowed.

"She knew Charles was in love with Camilla, Diana was in tears as she confided in her sisters that she couldn't marry him," the source reportedly told Globe Magazine. "But, her sisters told her it was too late to back out."
