Kanye West has revealed that he was diagnosed with a mental condition at the age of 39, and considers it a superpower that apparently helps fuel his creativity.

West, 40, talked about his diagnosis in an interview with radio personality Big Boy after debuting his new album, Ye, at a listening party in Wyomings Jackson Hole on Thursday.

I had never been diagnosed until I was like 39 years old, the rapper said, clarifying that he was diagnosed with a mental condition. But like I said on the album, he added, its not a disability, its a superpower.

The rapper didnt name the condition, but he has referred to bipolar disorder on Ye. The artwork for the album also features a photo of mountains, with a hand-written scrawl reading: I hate being bipolar its awesome.
