Amy Winehouse is ditching some of her best friends in a final attempt to beat her drink and drugs demons.

The 24-year-old singer has been ordered to get rid of hangers-on by worried bosses at her record label, Universal.

Together with her family they have launched an operation dubbed "Team Amy" to set up a safe house where she will live under constant surveillance, I can reveal.

Alienated: Amy Winehouse has cut off her friends in a bid to stay clean

The beehive-sporting star has cut off many old friends, including hairdresser Alex Foden, who lived in the same block of flats in East London and was with her when she was arrested for cannabis possession in Norway last year.

"Her best friend Alex is out of the picture," my source tells me.

"She has also been ditching the druggie losers she surrounded herself with. Her label are paying for 24/7 surveillance to help keep Amy clean."

The talented songstress, who performed at last week's Brits, attends daily outpatient sessions at the Capio Nightingale Clinic in North London and moved out of her home last week.

"The drug dealers who used to visit her still turned up at her house, and the people looking after Amy don't want her to be tempted," says my source.

Good influences: Mark Ronson, Kelly Osbourne and Blake Wood are reportedly planning to take a trip to New York with Amy

But I hear she is planning a trip to New York with Kelly Osbourne, music producer Mark Ronson and her new friend, teetotal photographer Blake Wood - a subject of friction between Amy and her drug addict husband Blake Fielder-Civil, who has been in Pentonville Prison since November.

"Blake doesn't want her to go. He is very jealous of her blossoming friendships with Mark and Blake II," I'm told.

"Last week Amy and Blake had a huge row and Blake tried to cut out one of his tattoos with Amy's name. He has also phoned Blake II to warn him to stay away from Amy."
