Cindy Crawford snapped up the chance to star in Taylor Swift's 'Bad Blood' music video.

The 49-year-old supermodel was approached by the '1989' pop star to play the part of the Headmistress in her 'Sin City' style mini-movie and jumped at the chance, saying ''sign me up'' before Taylor, 26, even had a chance to explain the concept to her.

Cindy revealed to Prestige Hong Kong magazine: ''Taylor got in touch with me and asked me to do it. Before she even explained the idea I was like, 'Sign me up!' I was honoured that she asked me. I really was. I think she was honoured that I said yes.''

Despite Taylor having signed up a galaxy of her star friends for 'Bad Blood' - including Lena Dunham, Selena Gomez, Kendall Jenner and Cara Delevingne - she was desperate for the queen of the 90s catwalk to take part.

And Cindy loved being able to ''connect'' with Taylor and her pals.

Cindy explained: ''I thought it was pretty cool that in some ways the young generation looks up to me. And it was a great way for me to connect to the younger generation ... Taylor's social media is huge. It was fun. She said she wanted to pay homage to my generation, so that was nice.''
