X Factor faces new drama as contestant Katie Waissel threatens to quit the show.
The 24-year-old feels that she has been subjected to a "bullying campaign", after she was put through to the final stages at the expense of Gamu Nhengu.
Viewers have been using the internet to promote her removal, urging members of the public not to vote for the eccentric blonde.
A show source said: "As outgoing and quirky as she is, she's only human and she is in tears over the bullying tactics people are using to get her out of the show.
"She collapsed in tears on Monday night, she hasn't been eating or sleeping."
On last weekend's first live show Katie was in the bottom three of the public vote, but was kept in when judge Louis Walsh made the key vote in her favour.
