Kanye West is in hospital recovering from exhaustion after cancelling his Saint Pablo Tour, according to various media reports.

Sources told NBC News that the rapper was taken to a hospital in Los Angeles after police answered a “medical welfare” call from his home. There was no criminal activity reported; the rapper was simply hospitalized for “his own health and safety” sources told NBC. Another source told People Magazine the rapper was exhausted and dealing with sleep deprivation.

His wife, Kim Kardashian West, was scheduled to attend the Angel Ball Monday, which would have been her first public appearance since she was robbed at gunpoint in Paris in October. 

Full refunds are being given for those who bought tickets to the Saint Pablo Tour, which was scheduled to run until December 31.
