WATCH: Kanye West Attacks Ray J in ‘Bound 2′ Surprise Performance

Ray J’s song “I Hit It First”, which bragged about his having sex with Kim Kardashian before Kanye West did was most likely the reason for the surprise lyric change in Kanye West’s performance last night on Late Night With Jimmy Fallon.

Kanye starts off his performance with some new words to the song, saying:

Brandy’s little sister lame man he know it now … When a real brother hold you down, you ‘sposed to drown.
