Inside Kanye West's Tumultuous 2016

The Grammy winner cancelled his tour this week and is currently in the hospital.

The cause, according to a source, was exhaustion and sleep deprivation. A rep for the star did not immediately respond to a request for comment, but the hospital visit, the source adds, was voluntarily and under the consultation of his physician.

West said he ran the lyric by Swift and she gave "her blessings." Swift's rep denied the account and said West did not call for the approval. This was in February and the back and forth carried on well into the summer, until West's wife posted a recording of the two artists talking about the song.

In the videos, Swift thanked West for the heads up, but originally said in February that he never mentioned calling her "that b----."

Also this year West tweeted a cryptic message that he was in serious debt.

"This Tidal Apple Beef is f------ up the music game," he exclaimed. West continued that he wanted to get the heads of the music giants together in the same room to work a deal out amid reports of a merger that could bring more music to fans.

"F--- all this d--- swinging contest. We all gon be dead in 100 Years. Let the kids have the music," he added.

Any rumored deal did not come to fruition. After Fortune and Forbes reported about the alleged talks between Apple and Tidal, Apple Music head Jimmy Lovine told BuzzFeed, “We’re not looking to acquire any streaming services.”

The Washington Post's fashion critic Robin Givhan wrote that West's show was "worse than bad."

West took these remarks in stride though, writing "Each and every one’s time, insight and feelings are invaluable to us. We want to make people feel great. Thank you for embarking on this creative journey."

ABC's "The View" later obtained and aired videos and photos of models falling down and fainting during the Yeezy show.

It was later confirmed that Kardashian West was robbed in a private mansion in Paris during Fashion Week and millions of dollars of jewelry were stolen. Khloe Kardashian later spoke to Ellen DeGeneres about her sister's recovery, saying she was "not doing that well."

"It's incredibly traumatic what happened to her, but our family is super close and great, and we'll get through it together," Khloe Kardashian added.

Then came the events of last week, starting with West saying that if he had in fact voted in the 2016 election, "I would have voted on Trump."

A few days later on Saturday night, he ranted more about Trump and criticized past collaborators and friends like Jay Z, even calling out President Barack Obama who he said "couldn't make America great." He arrived late and left the show early, dropping the mic.

He cancelled his show the next day, followed by the rest of his tour on Monday, then the hospitalization.
