Kanye West used to have sex with previous girlfriends while watching Kim Kardashian’s sex tape, according to reports.
The rapper is now dating Kardashian and has even written a recent song, 'Clique', which mentions the reality star's infamous tape and can be heard below.
But showbiz website TMZ says that West has used the tape of his current girlfriend in the past while making love to former girlfriends.
Kardashian's sex tape, which also features US singer Ray J, emerged in 2007 but was reportedly made in 2003.
It was also reported last week that Kardashian and Beyonce are struggling to become friends, despite the fact that West is a good friend of Beyonce's husband Jay-Z, while West pulled out of last week's MTC VMAs to be with his girlfriend.
