Amy Winehouse is on the verge of checking into rehab, a close friend said today.

The 23-year-old singer is "seriously considering" the move after emergency treatment in a London hospital for a suspected overdose.

Despite growing concern at her wild partying, the star had always said she would not seek professional help.

But a friend revealed she's "very close" to changing her mind, adding: "Amy got a massive fright when she was hospitalised and is finally coming round to everybody's pleadings with her to go to rehab.

The episode, hours after she was nominated for three MTV awards, forced her to pull out of two performances in Norway and Denmark.
