The model will return to the UK in the next few days

The 31-year-old left the Meadows Clinic in Arizona earlier this week after undergoing a month of therapy.

A spokeswoman for her modelling agency Storm said she was "looking forward to getting back to work".

Miss Moss was said to be "devastated" after newspaper revelations in September suggested she took cocaine.

'Personal issues'

She is spending time with friends in the US before returning to work and being reunited with her three-year-old daughter Lila, the spokeswoman said.

The Croydon-born model lost lucrative contracts with Chanel, H&M and Burberry after the Daily Mirror first reported the drugs claims.

Miss Moss then checked into the Meadows Clinic for a 30-day programme, saying she had "various personal issues" she needed to address.

Her spokeswoman said she was "in excellent spirits" and already had jobs lined up in Los Angeles, Paris and New York.

"She would like to thank everyone for their messages of support as they have played a major part in helping her," the spokeswoman said.

An investigation into the drugs allegations against Miss Moss was ordered personally by Scotland Yard chief Sir Ian Blair.
