Hollywood's action man John Travolta is all set to divulge details of his brief friendship with princess Diana, in his autobiography.

"I'm writing my book. If I wait any longer, it'll be two memoirs and I can't do that. I guess for readers in England the most interesting thing is going to be the stuff about Princess Diana," Travolta was quoted by Thisislondon as saying.

"It will include a lot of things I've never discussed with anybody," he added.

The Grease star met Diana in 1985 at a party hosted by President Ronald Reagan and asked for a dance after the hosts told Travolta that Diana was longing to dance with him.

Recollecting details of that evening Travolta said "I was at the lowest point of my career and yet in that room I felt like a frog who had been turned into a prince. I timidly crept over and said, 'Excuse me, princess, would you care to dance?' And she dipped her head and looked up at me and she blushed. Then she said, 'I would love to'.

"As they started playing songs from my movies they all left the floor. We were dancing alone. I said, 'God, we're in the middle of the floor with the whole world watching!' We had the time of our lives," he added.
