Millie Mackintosh has posed topless for Men's Health magazine.

Millie, who is married to hip-hop star Professor Green, took to Instagram to announce the news, writing: "Very proud to be in the October issue of @menshealthuk #fitnotthin #girlpower (sic)"

The picture of the beauty appears in black and white, and shows her covering her nipples with a resistance band.

The reality TV star has received criticism in some quarters for her slight frame, but Millie has hit back, saying her physique is the result of hard work in the gym rather than too much dieting.

Speaking to Women's Health magazine earlier this year, she said: "I get comments on Twitter or in interviews with people asking, 'How do you deal with the fact people think you're too thin?' I'm not too thin - I'm slim. I go to the gym to try to build muscle. I really try!"

She added: "I don't want to be skinny and I don't want a six-pack - I just want health... and some definition."
