That's unfair since you picked a picture of Gillian Mckeith when she was on that "i'm a celebrity" nonsense. It was an experience she wasn't enjoying and she had been taking care of her appearance.
Stress, a lack of sleep, no make up and untidy hair are not a good combination for a photograph. While Gillian Mckeith is obviously not a beautiful as Nigella Lawson, she doesn't exactly look bad for here age in her publicity shots.
