The British model's career has been in free fall since pictures of her snorting the narcotic with Doherty's band Babyshambles in a London recording studio were published in a British newspaper last month (15SEP05).
But the 26-year-old has cancelled the final three show of his band's UK tour on Thursday (13OCT05) so he can fly out to the Meadows Clinic to spend time with Moss. He will be following in the footsteps of JEFFERSON HACK, the father of Moss' three-year-old daughter, who has already visited her.
Doherty's uncle Phil, who is in regular contact with the rocker, says his nephew told him, "I can't wait to see Kate. I know Jefferson has been to see her already but she is not bothered about him.
"I have told her that as soon as the tour has finished I will be there. She is only allowed one visitor a day."
Phil adds, "Pete told me they are still very much an item and in love. He is just sex, drugs and rock 'n' roll - that's why Kate likes him."
The news of Doherty's impending arrival has been met with hostility from Moss' close friends and family who are convinced she needs to make a clean break from the F**K FOREVER frontman.
A family friend tells British newspaper The Sun, "Her mum LINDA wants her to get back with Jefferson. She and the rest of the family realise how much Kate loves Pete but they blame him for the mess she's in now."
