Kanye West was taken to UCLA Medical Center today around 1:30pm, from his Bel Air mansion just after he cancelled the rest of the dates on his Saint Pablo tour through the end of the year.

Police were called to the home for a welfare check and paramedics ended up responding and taking him to the hospital in handcuffs.

Meanwhile, Kim Kardashian is in New York to attend the Angel Ball honoring her late father Robert Kardashian. No word yet on whether she'll hop an early flight back to be by Kanye's side.

And just a thought ... since Kanye cancelled the remainder of his tour due to "exhaustion," could it be that insurance requires an actual medical diagnosis to cover the cost of the missed concert dates??? Otherwise, the reimbursement to the fans and to the concert promoter might have to come out of Kanye's pocket if he breaches his contract. Just a thought!
