In “Raising Kanye,” a new memoir of Kanye West’s youth in Chicago, Donda West says she repeatedly punished the rapper/producer for his interest in adult magazines and videos, which began when he was in fifth grade.

“I’ll never forget the day he took the X-rated magazine to school [and] was passing it around for the other boys to see and the teacher caught him,” the Chicago State University English Department chairwoman writes.

“When she asked him where he’d gotten the magazine, he said, ‘From my mother’s closet!’ . . . Before I knew it, I’d lost my temper and smacked him across the face.”

Donda borrowed Kanye’s VCR to watch a movie when the producer was a high school student – and discovered an ultra-hard-core porn tape inside.

“It was triple-X-rated and I was mad as hell.” To punish Kanye, she “required him to do a full-blown research paper complete with footnotes and bibliography . . . ‘The Impact of Watching X-rated Movies on a Teen-age Boy’ . . . Until he finished the paper to my satisfaction, there was to be no television, no going to play basketball, no friends over.”
