Various stars have thrown their support behind Kanye West amid news he has been hospitalized.

West was taken to the hospital Monday following months of touring on the Saint Pablo tour. The rapper had been in the news frequently over the past few weeks due to his various rants at his concerts, which he sometimes cut short or canceled altogether. He has since canceled the rest of his tour, which was set to last until Dec. 31. The rapper has also been dealing with the aftermath of his wife, Kim Kardashian West, being robbed in early October.

West has apparently been struggling with sleep, leading to his hospitalization for psychiatric evaluation. "He is exhausted and currently dealing with sleep deprivation," a source told People Monday. "He went to the hospital at will under the advice of his physician. He's fine."

The source also said that "he was not restrained" at the time and "he went freely."

In the wake of West's hospitalization, musicians and other celebrities have voiced their support of the rapper on Twitter.
