Royal blind item? "Which famous man is psychologically dependent on another?"

Source: Gawker.com

This is a very famous man, known all over the world. Very rich. Very spoilt. Very privileged. He’s married, happily, according to some. But there is a man in his life that he cannot let go. They are not lovers, although rumours have linked them together. It’s not even a bromance, yet our man has become psychologically dependent on his man. As someone who has professionally observed the relationship tells me, "Dependency is like love — a very powerful emotion. Love can be blind and extreme dependency can too. He sees what he wants to see. The other man can be Superman in his eyes.”

Princess Diana: The musical - "There was a time"

Princess Diana: I'm so miserable now (Spitting Image videoclip)

"Spitting Image" was "a British satirical puppet show that aired on the ITV network from 1984 to 1996" (source: Wikipedia). Nobody was off limits, including the Royal Family. Below is a 1992-93 clip in which Princess Diana bemoans her miserable life with Charles:

To put this clip in context, Andrew Morton's explosive biography of the princess had been published earlier that summer, which extensively cataloged her despair over her loveless marriage. In addition, the so-called "Squidgy tapes" had been leaked, in which Diana discussed her miserable Christmas with the royals.

 And yes, that is Jimmy Saville introducing Diana.
