Amy Winehouse has left rehab after one week.

The troubled 27-year-old singer - who has a history of drug addiction and heavy drinking -checked out of London's The Priory today (02.06.11) in order to undertake her summer touring commitments but will reportedly continue to be treated as an outpatient.

Her spokesman said: "She is now looking forward to playing shows around Europe this summer and is raring to go.

"She would like to send a huge thanks to all her fans for the messages of support she has received over the last week and can't wait to see them."

Amy's first concert appearance this summer will be at Kalemegdan Park in Serbia on June 18.

Amy reportedly stunned onlookers when she bought a small bottle of vodka from a shop in Southgate, north London, on her way rehab last month.

A source said: "She seemed out of it. She was stumbling about, slurring her words.

"I was shocked to see her buy vodka so early in the day, and even more shocked to see her knock it straight back."
