Kanye West has been hospitalized in Los Angeles after abruptly canceling the last 21 dates of his national tour.

A spokeswoman for the E! network, which airs the Kardashian family reality show and its spinoffs, confirmed that West was hospitalized Monday afternoon after his personal doctor called 911. Christel Wheeler said Tuesday that E! cameras were not filming when the 911 call was made and that they are not filming at Ronald Reagan UCLA Medical Center, where West is being treated.

A spokeswoman for West's wife, Kim Kardashian, had no comment Tuesday.

Los Angeles police told The Associated Press on Monday that they responded to a home in West Hollywood, California, and a person there was taken by ambulance to the hospital and placed on a psychiatric hold. Police did not identify the patient as West.

Wheeler said West was at the home of his personal trainer when the emergency call was made.
