Amy Winehouse has canceled the rest of her European summer concert tour after getting booed off stage during her performance in Serbia on June 18, according to the Associated Press.

The singer has also canceled all public performances. Her spokesperson told the wire service that Winehouse "is withdrawing from all scheduled performances" to focus on recovering. "Everyone involved wishes to do everything they can to help her return to her best and she will be given as long as it takes for this to happen," the spokesperson said.

Winehouse left rehab earlier this month for alcohol addiction, a week after checking herself in.

The 27-year-old British soul singer, known for the song "Rehab," checked herself into a treatment facility in London on May 25.

"She has completed her assessment at the Priory Clinic in London and will continue as an outpatient," the singer's publicist Tracey Miller said in a statement obtained by the Reuters news wire. "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."

Throughout the past few years, Winehouse appeared drunk at concerts, engaged in violent club confrontations and gradually lost weight. She was rushed to the hospital in 2007 after a drug overdose. She checked into a rehab clinic in January 2008 after the release of an online video that allegedly showed her smoking crack cocaine. Her father said later that year that Winehouse, a cigarette chain smoker, had developed the lung condition emphysema.

The concert which sparked the tour cancelation took place in Belgrade, Serbia's capital. The concert was supposed to kick off Winehouse's 12-date tour of Europe. After the performance it was announced the singer decided to cancel upcoming appearances in Istanbul and Athens, which were supposed to take place on June 20 and June 22 respectively. Her next scheduled concert date after Athens was on July 8 in Bilbao, Spain.

During her performance in Belgrade, which can be seen in a YouTube video below, the singer was booed after she arrived almost an hour late before stumbling to the stage and appearing unable to remember the lyrics to her songs.

According to U.K.'s Telegraph newspaper, she greeted the crowd in Serbia saying, "Hello Athens!" At one point she dropped the microphone, mumbled through her songs and occasionally disappeared.

Winehouse last recorded her own music in 2006, when she released the Grammy-winning album "Back to Black." Earlier this year, she performed concerts in Brazil.
