Kelly Rowland is in the process of choosing her final four female contestants for The X Factor live shows and insiders say she wants them to live like nuns for the rest of the series.

The Destinys Child star is whittling down her eight hopefuls to just four in Miami at present, and is being assisted by former American Idol contestant and Dreamgirls star Jennifer Hudson.

However before she picked her finalists, insiders say the judge sat them down and went through a lengthy list of rules, which includes no drinking, no sex and even no partying or loud shotuing, in case they damage their voices and affect their weekly performances.

Rowland told The Sun:

“There will be absolutely no alcohol, no smoking, no talking loud in clubs. I want them to take care of their bodies.”

“I will be like, ‘Don’t let anything knock you off your focus, or you will lose everything’.”

“I definitely have a schedule planned, I know what I’m doing.

“I have my vocal coach in there working with them now.”

She added:

“I am a softie but I’m tough too.”
