Chrissy Teigen says the worst thing about being a supermodel is ''not eating fried chicken''.

The 29-year-old beauty - who is married to 'Ordinary People' hitmaker John Legend - confessed the ugly truths of what it takes to be successful in the modelling industry.

Chrissy said: ''The thing not cool about being a model is I can't eat fried chicken every day.''

She also revealed the pain behind her recent injury on the US TV show 'Lip Sync Battle' - where the model DJs for the celebrities' musical performances.

She told People magazine: ''[The] worst my feet ever hurt was when I broke my foot on 'Lip Sync' two weeks ago.

''Someone did a cartwheel in the hall and I was all like, 'Yay', and then I cracked two bones.''

The Sports Illustrated model posted a photograph on Instagram of her injury wrapped up in bandages.

Meanwhile, Chrissy also revealed that her favourite John Legend song is 'Everybody Knows'.

She added: ''It's a kind of random song because I don't think it's anybody's favourite.''
