A Universal Music chief convinced Amy Winehouse to check into rehab by confronting her with a huge selection of press reports.

Amy's boss Lucian Grange hoped that the shock tactic would help the singer to realise the extent of her drugs problem.

"Lucian got his international marketing manager to find and copy every piece of press from around the world. It took the guy two days," a Universal source told The Sun.

"Lucian then laid everything out in his huge office and summoned Amy. He told her to have a good look, then tell him she hasn't got a problem with drugs. It did the trick."

Winehouse checked in to a rehab clinic on Thursday.
