Once you've had malaria there can be lifelong knock on effects on your general health and I wonder if she is just experiencing some exhaustion (real exhaustion, not the usual celebrity "three month hangover" exhaustion).

Like others are saying, she doesn't look "too thin" for not eating enough... She looks unwell. It's not just her weight. She looks pale, sunken and fragile. Like it's not just low body fat - there's just nothing to her. No muscle tone, either.

Its not about taking the piss or "trolling"... We found it genuinely sad watching her this year. She used to be so robust, athletic looking and full of energy on her earlier x factor stint years ago and at the moment she just doesn't. When she got up and danced in that live show... I was thinking "No Cheryl! You'll hurt yourself!".

I have tooth picks in my kitchen with more girth than her

No she has a Great Smile

She looks sick but I don't care for her at all so its non of my business. I do find it funny tho when obese girls on my fbook try to shade her, like sis can you worry about yourself.

Good grief arista, thank god you're not a doctor. Dying of cancer? Nah, great set of pearly whites there, I don't believe you.
