Rowland fell sick during a trip to Los Angeles.
“I’m 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. It got so bad that I stopped eating and drinking and got so dehydrated the doctor put me on a drip,” contactmusic.com quoted the 30-year-old as saying.
“Even now I can’t swallow anything – not even my own saliva… I was on the plane and I got this weird scratchy feeling in my throat…The doctor said that whatever I had was extremely rare. The infection is really low down in my throat,” she added.
“The X Factor” bosses have reportedly asked Pussycat Dolls star Nicole Scherzinger, a judge on the US version of the programme, to take Rowland’s place until she is better.
