Kanye West has canceled the remainder of his Saint Pablo tour after a week of rants and headline-grabbing incidents.

West has pulled the plug on all remaining tour dates in the Saint Pablo tour, which was set to run until Dec. 31. Tickets are being refunded for all remaining tour dates.

So why did West suddenly decide to cancel the rest of the tour? It's easy to speculate based on his recent behavior, including calling out various artists during rants and abruptly cancelling Sunday night's Los Angeles concert that he might be going through rough times, mentally and emotionally.

But a source told People that West is simply overworked and needs to take care of himself.

 "He's just exhausted," the source said. "He's been working around the clock on fashion design, both on his own line and the Adidas line. He's a notorious workaholic, so balancing both that work - which is extremely important to him - and the rigors of the tour every night, it really wore him out."

The source also suggested that his wife, Kim Kardashian West, may have influenced him.

"I'm sure Kim and his family played a part in the decision [to cancel the tour]," the source noted. "He's incredibly devoted to his family."

Kim is still trying to overcome the shocking Paris robbery that happened at the beginning of October, spending a lot of time with their children.

It remains to be seen if Kanye will return to tour again anytime soon, but based on recent behavior it looks like he'll be taking a much-needed break for a few months at the very least. Now-canceled tour dates include stops in Texas, Florida, New York, Pennsylvania, Ohio, Washington D.C. and Massachusetts.
