Amy Winehouse has pulled a stretch of European concerts after being admitted
to the hospital suffering from "severe exhaustion."

The artist was discharged from London's University College Hospital yesterday afternoon just hours after initially collapsing, according to a spokesperson for Island Records. Winehouse has been advised "to take complete rest," according to the spokesperson. As a result, upcoming performances in Norway and Denmark this week have been cancelled.

Winehouse's gigs at the V Festival's Chelmsford and Staffordshire sites on Aug. 18 and 19, respectively, are expected to go ahead as planned.

Island declined to comment on reports that Winehouse was given an adrenaline
shot and had her stomach pumped for a suspected drug overdose. Last weekend,
she performed at both Lollapalooza in Chicago and the V Festival in Baltimore.

The latest incident adds to a growing list of Winehouse cancellations, which include pulling out of Scotland's T in the Park festival and Liverpool's Summer Pops.

Winehouse, who has a reputation for heavy drinking and hard partying, also made headlines in March when she was unable to perform at a concert at London's Shepherds Bush Empire in London.

At the Ivor Novello Awards in May, where she won the best contemporary song award for her hit "Rehab," she joked, "I didn't even have time to get drunk. I've only been here for 15 minutes."

Winehouse has become a bona-fide superstar with the release of her sophomore album "Back To Black." The album has achieved IFPI Platinum Europe status, for pan-European shipments in excess of 1 million units, and is certified four-time platinum (1.2 million units) in the United Kingdom, where it is currently No. 8 on the albums chart after 40 weeks.

Critics have rewarded "Back To Black" with a nomination for the 2007 Mercury Music Prize. Her debut album, "Frank," was nominated in 2004.
