Kelly Rowland quits X-factor?

Destiny's Child star Kelly Rowland unexpectedly pulled out of last night's X- factor show after being struck with a throat infection. Last week on the show, Tulisa sparked up a row after she accused Misha B of bullying the girls in Rythmix and making them cry. Kelly was outraged by the claims, and was furious that Tulisa had brought it up while the show was on-air. Last night, a teary-eyed Kelly denied her absence to the show was connected with the argument, saying:"I am so sick. I have no idea what is wrong with me, but i have the worst sore throat. I've  been in tears all week." She then goes on to tell us it got so bad she was forced to stop eating and drinking, and that she was so dehydrated the doctor put her on a drip. And to make matters worse, Louis Walsh then joined the argument, calling Misha B a bully.

Once friends: Kelly and Tulisa on the X-Factor

 The argument has now become so out of hand, that the two judges, once friends, are no longer on speaking terms. Last night on the show, Tulisa said:"We are not speaking. I'm getting on with it. I'm mature enough to take it on the chin. She can talk to me and we can sort it out, but if she doesn't, we don't have to talk." she then goes on to say: "If we don't speak a anymore, its because she doesn't want to speak to me. I don't feel I have to apologise and make the first move because I've done  nothing wrong." Meanwhile, Kelly has flown back to her home in the states, and insits she has been in touch with her girls every day. Ahhh! We'll be thinking of you, Kelly!
