Troubled rocker Pete Doherty has been accused of taking drugs in a Thailand hostel, just two days after he and Kate Moss's New Year's Day blessing.

A British newspaper has published snaps of the star surrounded by drug paraphernalia and appearing to inject a substance into his arm.

They were taken by an Australian backpacker who claims Doherty took drugs in her hostel room while talking to the supermodel on a mobile phone.

Jess Lea claims she and a friend recognised the singer and invited him back to their room after spotting him buying needles from a drug store in the Thai resort of Phuket.

Lea claims Doherty sneaked off from Moss to buy drugs just days after the pair's romantic ceremony - but the rocker was bombarded by phone-calls from the supermodel.

The 21-year-old tells The Sun, "She did seem quit pissed off, with him constantly pleading, 'What's wrong? I love you.'"

When she asked if he would marry Moss, Doherty told Lea and her pal, "No. I love her but I wouldn't marry her if she was the last woman on earth. She's too paranoid."

Back in Britain, Doherty and Moss were yesterday seen checking into a London rehab clinic, where the supermodel reportedly plans to help her addict lover finally kick his drug addictions.
