Naomi Campbell thinks Kate Moss is incomparable.

The supermodel doesn't agree with people trying to label Cara Delevingne 'the new Kate' because, while the model of the moment might be talented, she feels her old friend Kate is one of a kind.

She told the Mail On Sunday: ''Cara is Cara Delevingne, Kate is Kate Moss. People are just saying that because she is the same height as Kate. But there is only going to be one Kate Moss. Kate is an icon.

''Cara may become an icon: who knows how long she wants to do it for? It has just begun for her and she is doing amazingly well... I was actually asked to speak to Cara, but I don't know her very well.

''I've met her a few times and she's been very pleasant. I haven't spoken to her properly yet. For me the timing has to be right.''

The 43-year-old star has had a soft spot for her fellow supermodel Kate since she mentored her to superstardom in the 90s, and believes that's where her passion for finding budding models on her reality TV show 'The Face' has come from.

Naomi said: ''I love mentoring young girls. I've always been like that. When I told Kate Moss about the show, how I was mentoring these young girls, she watched the US show and then she said, 'Naomi, I was your first.'

''It's true. I looked after her when she first started out; she lived with me in New York. She was amazing already: she had the book, she had the jobs, but I'd tell her what people were like, how she should be with certain people.

''We're still good friends. All of us [supermodels], we've all stayed close, we're all still there.''
