The Babyshambles frontman travelled to The Meadows Clinic in Arizona on Saturday (19NOV05) after Moss begged him to seek help for his addiction to crack cocaine.
Last month, Doherty - who has enjoyed several unsuccessful spells in rehab in the past - said, "She wants me to go into this place in Arizona, straight after her and do it.
"Maybe she just wants me to go through it. It's the only time I'll have f**king voluntarily gone into rehab."
Moss spent several weeks in The Meadows after a British newspaper published pictures of her snorting cocaine.
