The supermodel formed a close friendship with Amal after she wed George Clooney last year (Sep14), and now she enjoys double date nights with her husband, Rande Gerber, and the Clooneys - and her new buddy is always a delight to talk to.

"I think one of the things I love about Amal is that she's not only interesting - she's very interesting to talk to - but she's also interested in your world as well," Cindy told People at the Miami, Florida launch of her book Becoming Cindy on Tuesday night (06Oct15). She can talk to my kids about their thing, or she'll talk to me about my book or my business."

While Cindy has earned her reputation as a fashion icon thanks to her 30 year modelling career, Amal has managed to achieve a similar status in just a short few months thanks to her stylish appearance, but Cindy insists she and her new pal usually have more important things to discuss than the world of fashion.

"Amal is an incredibly fashionable person, so she doesn't need my advice," Cindy said. "I guess we talk about fashion in a way, but it's not like we pore over magazines together. It's more like, she'll ask me, 'Who is your favourite photographer'. She's interested in my life, just like I'm interested in her life."
