Amy Winehouse is out. Time will tell if behavioral changes are in.

A rep for the "Rehab" singer confirms to E! News that the 24-year-old was officially discharged as a patient from the London Clinic yesterday after a whirlwind stay, which included a diagnosis of early stages of emphysema and two days out to perform at various gigs around England.

"I can confirm that Amy has left the London Clinic and will be treated as an outpatient," Tracey Miller said.

As an outpatient, Winehouse is expected to return to the hospital for regular checkups. Despite her father's initial public diagnosis of emphysema, Winehouse's camp later clarified the singer is suffering from early-stage symptoms of the chronic respiratory disease.

Winehouse was first admitted to the hospital last month after suffering a fainting spell at her home. She was apparently deemed well enough to be excused from the ward on two high-profile occasions, which had two rather varied rates of success.

The first saw a healthy-looking Winehouse take the stage at Nelson Mandela's special 90th birthday concert, in which she sang two slur-free tunes before returning to the clinic.

The second was more in line with a performance fans have come to expect from the Grammy winner, and took place over the weekend at England's famed Glastonbury festival. After her performance, a concertgoer threw a hat at her head and, after mistakenly identifying the offending chapeau tosser, Winehouse lashed out and belted a seemingly innocent fan. All of which was, in the great British tabloid tradition, caught on tape.

On the bright side, things can only get better.
