It's true - apparently dancing with the then-being-cuckolded Princess of Wales turned around Travolta's career:
Travolta revealed how then-First Lady Nancy Reagan took him aside at the 1985 glittering gala and quietly told him that Diana had specially requested to dance with him.
He was told to wait until midnight before approaching her. At the stroke of 12, he crept over nervously and asked: "Excuse me, princess, would you care to dance?"
Travolta said: "I looked her in the eye and said, 'We're good. I can do this.'"
Grease and Saturday Night Fever star Travolta said: "That was an amazing moment because I was having a dip in my career and no one was interested in me.
"Suddenly, I was the only thing that mattered in America to Princess Diana and I was reborn. I was like, 'Wow!
I matter to someone again.' I was on the cover of every newspaper and magazine in the world and someone as significant as Princess Diana reminded everyone of me.
And, indeed, just, erm, nine short years later, Travolta made Pulp Fiction. The career-reviving power of Di might be amazing, but apparently it works incredibly slowly indeed.
