Friends of 'X Factor' hopeful Cher Lloyd have expressed concerns for the frail, teenager according to one report.

The Daily Star says producers on the show have been told to keep an eye on the hotly tipped 17-year-old singer after claims that she has become frail and nervy.

A source is quoted in the newspaper as saying "She is new to this, like all the contestants, and because of her age we are making sure she is prepared for what could happen to her. But if we thought she would suffer in any way in this contest we would not have put her through.

"The X Factor is a big deal and you do need nerves of steel to get through it every week. Contestants are separated from everything and everyone they know and are expected to work long and tiring days to prepare.

"Cher is from a small town and has a tight-knit group of friends. She is also from a huge family that everyone in Malvern knows, and she will hate being without them all. She will be a nervous wreck, we just hope it won’t break her."

Cher has claimed her nerves are not unusual saying "I always get nervous before I sing, to the stage where people think I am not going to be able to do it. Then when I get on stage I am fine."

The singer impressed the judging panel and audience with her version of Soulja Boy’s 'Turn My Swag On' and she is expected to make it through the bootcamp stage to the live shows.
