Jourdan Dunn claims she was axed from a Christian Dior fashion show because of her breasts.

The 22-year-old model was set to walk the runway at the fashion house's haute couture show in Paris, France, yesterday (01.07.13) but was allegedly told her services were no longer required due to her ample assets.

She wrote on her Twitter account: ''Ahahahahahaha I just [got] cancelled from Dior because of my boobs! I ❤ fashion #Couture (sic)''

The British beauty - who is one of the few prominent black models in the industry - went on to reveal that she is often axed from runway shows because of the colour of her skin.

She added: ''I'm normally told I'm cancelled because I'm 'coloured' so being cancelled because [of] my boobs is a minor : ) (sic)''

Dior has recently come under fire for the lack of diversity in its runway shows, with insiders suggesting the luxury brand has almost exclusively cast white models since Raf Simons took over as creative director in April 2012.

Although Jourdan didn't walk Dior's show in Paris yesterday, perhaps in a bid to silence the critics, the luxury brand did feature several black models on the runway - including Alek Wek, Grace Mahary, Joan Smalls, Maria Borges, Kelly Moreira and Yasmin Warsame.

Jourdan is no stranger to helping fashion brands diversify their catwalk shows as in 2008 she became the first black model to walk a Prada show in over a decade.
