Kanye West has reportedly been admitted to hospital for 'exhaustion', a day after cancelling his tour following a bizarre rant on stage.
The rapper is being treated for sleep deprivation in Los Angeles after police were called to reports of a disturbance on Monday, according to reports in People magazine.
"He is exhausted and currently dealing with sleep deprivation," they quote a source as saying. "He went to the hospital at will under the advice of his physician. He's fine."
The source added that West was not restrained and that "he went freely" to hospital.
The Los Angeles Police Department confirmed it responded to a report of disturbance but the incident was deemed a "medical emergency".
A Los Angeles Fire Department spokesman said: "At 1.20pm, the Los Angeles Fire Department responded to an unspecified medical aid request in the 900 block of North Laurel Avenue.
"An adult male described as medically stable was taken to an area hospital for assessment."
West was due to play The Forum, an indoor arena in LA as part of his Saint Pablo Tour on Sunday, however less than three hours before it began the venue sent out a tweet to say the show was being scrapped and that ticket-holders should seek a refund.
It came just a day after he stopped a show after just three songs and after launching into a bizarre tirade, with some colourful language, against the likes of Beyoncé and Hillary Clinton on stage.
West's wife Kim Kardashian was expected to appear at the Angel Ball in New York City on Monday but did not attend. It would have marked her first public appearance since she was robbed in Paris in early October.
Kardashian's mother Kris Jenner did attend the Angel Ball however and described West as "exhausted" after a "gruelling tour".
She spoke to reporters in New York shortly before the news broke about her son-in-law's reported hospital treatment.
Addressing why West had cancelled his tour, Jenner told US TV show Extra: "He's exhausted, he's just really tired. He's had a gruelling tour and it's been a grind so he just needs some rest."
