Kanye West is reportedly receiving treatment and was placed under assessment in hospital, just a day after cancelling his Life of Saint Pablo Tour.
He was taken to a hospital in Los Angeles after police responded to calls on Monday afternoon.
It has been reported that Kanye is being treated for sleep deprivation and exhaustion, according to People magazine.
"He is exhausted and currently dealing with sleep deprivation,” a source told the magazine.
"He went to the hospital at will under the advice of his physician. He's fine."
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'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.
It is unclear if Kanye remains in hospital, however the rapper's concert promoter, Live Nation, confirmed that the 39-year-old will not be performing the remaining dates of his Saint Pablo Tour.
Kanye's friends fear the star is reportedly suffering from "nervous exhaustion".
