Actor Nigel Havers struck up a close friendship with the late royal and the pair would regularly have tea together.

Speaking on Piers Morgan's Life Stories, he said: "She did come and have tea a couple of times ... it was very much just tea. I was very, very good. No I wasn't in love with her but I did adore her. Adored is different to in love.

"And also she was married to Prince Charles. He would have been really cross with me. What an incredibly bad thing to do. It was random but it was rather charming. I made a very good cup of tea. She'd say that life was difficult ... she was keen to have a conversation with me, just saying hi, what was I up to and stuff like that."

Meanwhile, singer and television personality Sinitta previously opened up about the Princess' "most delicious sense of humour".

The 53-year-old star said: "We made friends at the Harbour Club and shared the same personal trainer. What Diana and I had most in common were the same friends in the club. Both of us were also ballet trained, so we would always have a chat on our own on the mats in the stretching area.

"Our friend Christopher Whalley used to call us Ebony and Ivory, as if we were a little double act! Diana was extremely fit, more fit than her fragile frame would have you imagine.

"I also used to like to tell her the gym gossip and make her giggle - we had nicknames for a lot of the regulars. She had the most delicious sense of humour!"
