The `Fight for This Love` singer - who has had to take a break from all her commitments after she was struck down with potentially fatal tropical disease malaria - has reportedly been texting Simon Cowell saying she is bored and wants to resume her role as a judge on his British pop star search show `The X Factor` as soon as possible.
Speaking to `GMTV`, Simon said: "The worst is over. The texts are getting increasingly feisty so she`s on the mend."
However, the music mogul admitted he is trying to stop the 27-year-old brunette beauty - who is believed to have contracted the illness while on holiday with rumoured boyfriend Derek Hough in Tanzania last month - from rushing back to work too quickly.
He explained: "It was serious and she was ill - we didn`t realise how ill. But judging by the text messages I`ve had, she is definitely looking forward to getting back to work.
"I think our job is to make sure she doesn`t come back too quickly because I think she`s bored out of her mind and going crazy."
Cheryl - who as well as pulling out of `The X Factor` had to cancel her scheduled appearances at the V Festival in August - was discharged from hospital last Thursday morning (15.06.10) and is now convalescing at her home in Surrey, South England.
