Kanye West raps about having sex with Kim Kardashian in a new remix.

The 'New Slaves' star appears on a version of 'Drunk in Love' by Beyonce, where he boasts his fiancee is a ''M.I.L.F.'' and talks about having oral sex with her.

The rap includes the lines: ''You will never need another lover / 'Cause you a M.I.L.F. and I'm a mother*****r ... I ain't no pastor, don't do missionary / I know good p***y when I see it, I'm a visionary ... I impregnated your mouth girl, ooh / that's when I knew you could be my spouse, girl.''

Kanye also makes reference to the infamous video for his track 'Bound2', in which Kim, 33, appeared naked, straddling him on a motorbike.

He raps: ''If you aint on sight, you on Skype / I put you on a bike, you bound girl.''

However the 36-year-old rapper did show a more romantic side for Valentine's Day yesterday (14.02.14) when he surprised his wife-to-be with a room full of roses as she arrived in Baltimore with their eight-month-old daughter, North, to watch him perform a concert in his Yeezus tour.

Kim wrote on Twitter: ''A thousand roses! Nothing better than being with my love on Valentine's Day! Happy Vday dolls! (sic)''
