Naomi Campbell has hinted she isn't impressed by Kim Kardashian and Kanye West's VOGUE cover.

The supermodel, who has appeared on the front of the US magazine numerous times during her 28-year career, spoke about the controversial cover featuring the reality star and her rapper husband on Australia's 'The Morning Show' yesterday (25.03.14).

When host Kylie Gillies asked the 43-year-old beauty what she thought about the cover, she started laughing and replied: ''I'm a fashion model ... I do not want to comment.''

She then added: ''Because I'm a fashion model and I've been working for 28 years and when you get a VOGUE cover it's a build in your career, it's a stepping stone to achieve that.

''And you know I'm a fashion model so what more can I say.''

Kylie then asked her: ''So you think Kim and Kanye haven't earned the right to be on the cover?''

Naomi thought carefully about her reply and insisted it was down to VOGUE editor Anna Wintour to know what's right for the magazine.

She said: ''Those are your words, I'm being politically correct. That's Anna Wintour's choice to put them on the cover of her magazine, who's to question it?''

The cover features Kim in a wedding dress as the couple prepare for their upcoming wedding in May and further images inside the magazine show the pair cuddling up to their nine-month-old baby North.

Meanwhile, Naomi also recently slammed Nicole Trunfio, her fellow mentor on modelling show 'The Face Australia'.

She said: '''Nicole was disrespectful, in a sense where instead of trying to get to know me she said I wasn't a model of now.

''And at the time when she said it I was on four magazine covers around the world, two of them being VOGUE.''
