The former Destiny’s Child singer is playing host to eight semi-finalists at her Miami home and has ordered the girls to stay away from booze and boys.
Having not gone out by herself until she was 22, teetotaller Kelly said she wants to teach the girls the importance of living well.
'There will be absolutely no alcohol, no smoking, no talking loud in clubs. I want them to take care of their bodies,” she told The Sun. “I didn't party until two years ago.'
And when it comes to relationships, 'I will be like, 'Don't let anything knock you off your focus, or you will lose everything'.'
She plans to make her contestants the best, using her personal vocal coach Rob Stevens and his iPhone app, Voice Tutor.
'I definitely have a schedule planned. I know what I'm doing. I have my vocal coach in there working with them now.'
And she won’t take any slacking off. 'I am a softie but I'm tough too.'
