Kelly was particularly upset because her illness meant she had to miss attending the LA Art Show at the Los Angeles Convention Center and could no longer get her hands on a piece of art she wanted to buy.

Replying to artist Jessicka Adams, who had posted a picture of a piece entitled 'Joy Was Her Name', which depicted a crying girl with cats in place of her hair, she wrote:

@Jessicka @SloanFineArt @LAArtShow Im so dumbed Im sick I wanted to go tomorrow so badly! ps pissed this already sold I wanted to buy it ;(

The 30-year-old presenter recently bemoaned the fact she can't take a good selfie as she always looks "psychotic in the photographs she takes of herself".

Every time I try to take a selfie I look like a fucking borderline psychotic! Why can't I be one of "those girls" it just #Farts good selfies? ??
