Kelly Osbourne was embarrassed after her builder saw her naked.

The 'Fashion Police' star is having renovations done at her Los Angeles home and was left red-faced when one of the workmen walked into her bedroom while she was getting changed.

She tweeted: ''#DyingRightNow getting work done on my house & one of the builders just walked into my bedroom while i was half naked! my face is so red (sic).''

Even though the 28-year-old star has shed more than 60 pounds over the last two years, she previously admitted she still struggles with her body image.

She said: ''I'll never be the kind of person who thinks, 'I'm so hot.' I don't want to be. But I learnt to respect and love myself - something I didn't think I would ever be capable of.

'''At the Emmys last year I had my first moment when I really felt good. I put on my dress and when I looked at myself in the mirror I cried. Never in my life did I think that Zac Posen would fly in a dress for me that he could have given to any nominee. It fitted me perfectly!''

Kelly has swapped dairy, meat and fast food for a diet rich in vegetables, fruit, nuts and seeds and is also committed to a rigorous exercise regime.

This combination, which she and boyfriend Matthew Mosshart follow, has resulted in Kelly being the healthiest she has ever been.

She explained: ''I'm happy with how I look now. As long as I'm healthy, do exercise and eat right, that's the main thing. I'm slim now, but I don't want to be anorexic. I love Matthew and we love to work out together - we motivate one another. I go on the treadmill every day for half an hour and do two hours of exercise if I have a special event.''
