The 63-year-old actress was rumoured to have started dating Travolta after playing lovers in the 1970 musical, but talking to The Sun, she confirmed that there was no truth to the speculation.
“There was a lot of gossip about John and I having a relationship,” she said. “The fact I was in the middle of a pretty long break-up with Lee Kramer (her former boyfriend and manager) at the time made it even worse.
“The truth was we were just good friends and used to hang around together, going for drinks or a meal. But there was nothing in it.”
She added, “He still remains a friend today. It was the same with Cliff Richard when we worked together in London in the 1970s. We connected in a great way. He was — and is — a lovely man.”
