Lancashire: Wham! Last Christmas model recalls 'hilarious' video ...

Regarding the famous dinner table scene featuring the pair's eyes meeting over glasses of red wine, she said: "At one point I couldn't drink anymore.

"You can see in that shot where George is looking at me and I'm looking back, I'm pretending to drink the wine because, honestly, Andrew [Ridgeley] and I had so much. It was just hilarious."

In real life she had then been in a relationship with the musician Vangelis, who had won an Oscar for the theme to the 1981 Chariots of Fire film.

She even wore his long grey coat during the making of the video.

"He didn't want me to go [to Switzerland] because George was impossibly handsome and he said I will pay you if you don't go – and I wouldn't have taken it anyway but I'm just so glad that I did it," she said.

Although George Michael did have relationships with women in the earlier part of his career, he publicly revealed he was gay in 1998.

He died on Christmas Day in 2016 and Hill remembers him as "a gorgeous soul".

She believes Last Christmas "spans the generations", saying that both her 96-year-old mother and 33-year-old twin children love the track.

"The song itself sounds incredibly fresh – it's like the first time you've ever heard it really, it's so beautifully written.

"We had a fantastic time – I absolutely loved it and I'm so lucky to have been in it."
