Kanye West has been hospitalized after abruptly canceling the last 21 dates of his national tour, according to reports from several media outlets.

West's personal doctor is reported to have made the 911 call Monday that resulted in the rapper's hospitalization. Dr. Michael Farzam told police that his patient, “Jim Jones,” had temporary psychosis as a result of sleep deprivation and dehydration, TMZ on Tuesday quoted law enforcement sources as saying.

Citing anonymous law enforcement sources and West representatives, the media outlets reported that the hip-hop superstar was taken to Ronald Reagan UCLA Medical Center in Los Angeles on Monday afternoon because of stress and exhaustion and spent the night there for his own safety.

Without confirming that the patient was West, Los Angeles police told the Associated Press that officers were called to a house on Laurel Avenue near West Hollywood for a disturbance about 1:20 p.m. Monday. When they arrived, it was clear it was a medical situation. Police told the AP that the patient was taken in an ambulance to the hospital and placed on a psychiatric hold.

Representatives for West and his wife, Kim Kardashian, did not reply to several messages left by the AP seeking confirmation or comment. The hospitalization was first reported by NBC News.
