Kate Moss has checked herself into rehab in a bid to kick her cocaine addiction.

The stunning supermodel, who earlier this month was pictured snorting lines of the Class A substance, will undergo 30 days intensive treatment in the renowned Meadows centre, in Phoenix, Arizona, to cure her of her drug addiction.

Kate flew out to the US on Saturday (24.09.05) by private jet and will now be cut off from the outside world for the duration of the course.

The 31-year-old beauty is even banned from contacting anyone by telephone and is missing her daughter Lila Grace's third birthday today (29.09.05) to battle her addiction.

As well as tackle her drug problem, Kate will also deal with other negative issues in her life.

It is believed the catwalk queen - who has been dropped by several top fashion houses, including Chanel, Burberry and H&M following her cocaine exposé - checked into the centre on the advice of fellow model Elle Macpherson who was treated at the clinic for depression in 2003.

During her stay, Kate will share a room with two other women and talk about her addiction in regular group therapy sessions, and also have to give up numerous luxuries, including cigarettes.
