Pete Doherty Visits Amy Winehouse At 4am

Amy Winehouse was visited by Pete Doherty at 4am yesterday morning.

The Babyshambles rocker was seen entering the east London home of one of Amy's friends carrying a guitar and had a "suspicious" dusting of white powder on his trousers.

A source said: "Pete arrived at four in the morning looking the worse for wear and carrying his guitar. He had some sort of white powder spilt on his trousers."

Pete - who recently vowed he was drugs free despite being caught on video snorting cocaine and injecting heroin on two separate occasions - also appeared to have sores and cuts on his face and dirty hands.

The pair are believed to be working together on a duet called 'You Hurt The Ones You Love', but Pete, 28, has previously confessed to taking drugs with troubled Amy.

Amy, 24, moved her possessions - which included a clear bag containing a suspicious white powder and a box of CDs - from her north London home to her pal's house in Bow on Monday (03.12.07). The 'Rehab' singer has bought a new home in the area and is waiting to move in. Earlier on Monday, she had wandered the streets, clothed but barefoot, to beg a cigarette from some builders working in the area.

One workman said: "She had no make-up on and no shoes. It was sad. She must have a fortune in the bank but was wandering around like a tramp looking for a smoke."

Last week, Amy cancelled her British tour on doctors' orders after struggling to cope with husband Blake Fielder-Civil's imprisonment. Blake is currently in remand at London's Pentonville Prison awaiting trial on charges of assault and attempting to pervert the course of justice. Since Blake was refused bail, his mother Georgette claims Amy has been taking "more drugs than ever".
