Cheryl Cole 'too negative for X Factor USA'

Cheryl Cole was reportedly fired from The X Factor USA for having a "negative" attitude. 
The 'Promise This' singer, who has allegedly been replaced on the Fox contest by host Nicole Scherzinger, is said to have angered network bosses for refusing to adapt to her new life and promote herself in America. 
A Fox production executive told The Mirror: "Instead of attending the Grammy Awards and the Coachella music festival, putting herself out there in America, she sat in her hotel room eating ­digestive biscuits."
A friend added: "She just seemed very down. There was too much negativity around her. It's as if she still regrets getting divorced from Ashley Cole, when clearly she was still in love with him.
"She just didn't help herself. She was ­offered elocution ­lessons and said, 'No'. She was offered a stylist and said, 'No'.
"And then she came out on the first day ­wearing that hideous outfit. And the reaction from Fox was like, 'What the f**k is she ­wearing?'."
Meanwhile, another insider commented that Cole failed to appear excited about her new role during auditions for the show.
They said: "Cheryl seemed uncomfortable as if she didn't like judging the acts. And at the end of the day that isn't what the TV execs wanted."
The paper also claims that Cole's fellow judge Paula Abdul was so concerned by the 27-year-old's behaviour that she suggested using "crystal healing" to improve her mood. 
Cole has reportedly failed to win back her spot on the UK X Factor panel, with N-Dubz star Tulisa Contostavlos tonight touted as her replacement.
