In Touch previously reported that Kim Kardashian has been diagnosed with a serious illness — and now we know how her husband, Kanye West, reacted when he found out about her health condition.

Sources say this is what led to Yeezy's most recent concert rant, when he slammed his estranged pals Jay Z and Beyoncé before storming off the stage and cancelling the rest of his tour. He was hospitalized shortly after.

"This has nothing to do with Beyoncé," TheDirty.com founder Nik Richie, who first received knowledge of the diagnosis, tells In Touch. "Kanye is in his head right now because he believes he's cursed. His wife got diagnosed with something really bad and Kanye can't handle it. Everyone he loves, he loses."
