On Saturday, Westreleased new song“XTCY” with DJ Clark Kent, in which he openly admitted to having “sick thoughts” about sisters-in-lawKourtney Kardashian,Khloé Kardashian,Kendall JennerandKylie Jenner.
“You got sick thoughts? I got more of ’em/ You got a sister-in-law you would smash? I got four of them,” West raps in the first verse.
A source tells PEOPLE that the 41-year-old rapper often goes over the lyrics to his songs with wife Kim Kardashian West, so it’s unlikely that her siblings wouldn’t have known about the explicit lyrics in advance — and they might not have been bothered, anyway.

When asked about the song after calling into the Australian radio showKylie and Jackie Oon Tuesday,Kris Jennerjokingly tried to feign ignorance.
“I have earmuffs on right now. I did not know,” the Keeping Up with the Kardashians matriarch, 62, said. “I just walk around with my hands over my ears. Earmuffs, earmuffs!”
