Kanye West Hospitalized for Exhaustion in L.A. After Abruptly Canceling Tour

Kanye West is under observation at a Los Angeles hospital following an abrupt cancellation of his concert tour on Monday.

A source close to West's family told CNN that the rapper is being treated for "exhaustion" at UCLA Medical Center.

Police initially responded to a disturbance call around 1:20 p.m., but officers realized it was a medical emergency only when they got there, according to the Los Angeles Police Department. Fire officials confirmed the call involved Kanye West.

According to Brian Humphrey, of the Los Angeles Fire Department, an adult male, described as medically stable, was transported to a local hospital for further assessment.

West's wife, Kim Kardashian West, was in New York Monday to attend a charity event where her late father was being honored, but she flew back to Los Angeles when she learned of her husband's situation, the source said.

West's concert promoter, Live Nation, announced earlier Monday that the remaining dates of his Saint Pablo Tour — scheduled through New Years Eve — had been called off.

It was the latest twist in what has been several days of bizarre behavior from the artist.

Controversy started Thursday night during West's concert in San Jose, when he declared that he hadn't voted in the recent election, but he would have cast his ballot for now President-elect Donald Trump.

West also offered his opinion about why he wishes black people would stop talking about racism.

On Saturday, the rapper ended his concert in Sacramento after performing just two songs and going off about Hillary Clinton, Google, Facebook, Beyonce and Jay Z.

The following night, he canceled his show in Los Angeles.

Even Snoop Dogg scratched his head over West's recent tirades.

An expletive filled video of Snoop declaring West's latest rhetoric "crazy" has gone viral.

"I smoke weed," Snoop said. "Weed don't make you do that. What the f*** is he on?"

On Sunday, West, who in September tweeted "I got rid of my phone so I can have air to create," began posting unidentified fashion images on his Instagram account that appear to be from vintage Maison Margiela lookbooks.

It was all a disappointment to more than a few fans.

But rapper Talib Kweli tweeted some words of support for West.

"@kanyewest we love u. u r everything u say u are," Kweli tweeted. "A genius, an icon. U added greatness to my life. But lifting Trump up kills us. Come home."
