The 'Stronger' rapper - who has been dating the Kardashian reality TV star for around five months - appears to make reference to Kim's infamous 2007 tape in latest track 'Clique'.
The sex tape stars Kardashian and her ex-boyfriend Ray J, and after it was leaked online, the 31-year-old socialite became a huge star.
While he is singing about the sex tape, it was recently claimed West - who has known Kardashian for four years - had refused to watch it.
A source said, "For all his bad-boy image, he's quite old-fashioned and [while they were still just friends] he thought it inappropriate to view Kim's tape. Now that they are a couple, there's no way Kanye's ever going to look at it."
The 'Gotta Have It' hitmaker is so sensitive about the sex tape - which features Kim and Ray J participating in a variety of erotic acts - he won't even let anyone in his entourage or circle of friends talk about it.
