Simon Cowell advises Cheryl Cole to stay single

Music mogul Simon Cowell wants The X Factor co-judge Cheryl Cole to stay single and focus on her health.

"Simon has had serious words with Cheryl and gave her a list of things she needs to sort out," Contactmusic.com quoted a source as saying.

"He's demanded that she puts her love life on hold - he feels Derek Hough (her boyfriend) is a distraction that she simply doesn't need. Derek is always hanging around on the set with her and Cheryl is constantly trying to keep him happy," the source said.

Simon, 50, is also said to be planning to find a lifestyle coach to help Cheryl cope with her hectic schedule.

"Simon wants Cheryl to accept more help, rather than try and battle on by herself. He told her that everyone in the US has a lifestyle guru and that he will get someone to work with her."

"Cheryl hates the idea because she is a very private person, but Simon is insisting on it. He believes having someone with her is the only way to guarantee she will eat, sleep and talk about her problems," the source added.
