Amy Winehouse treated for exhaustion

Rehab singer Amy Winehouse was hospitalized this morning for exhaustion. "Amy was admitted to London's University College London Hospital for exhaustion, treated and released just this afternoon," Winehouse's rep said. "The doctor said she was suffering from severe exhaustion, and she was told to rest... Amy has been pulled in a million directions. She has done hundreds of shows and promotional appearances in the last year, often working 16-hour days. It's bound to catch up with anybody."
