Ray J might have 'Hit It First,' but Kanye West knows how to get the last laugh, delivering a scathing diss during a live performance of 'Bound 2' on 'Late Night With Jimmy Fallon.'Kanye began his first verse using modified lyrics, saying "Brandy's little sister lame man he know it now/When a real brother hold you down you 'sposed to drown." Kanye is clearly going at Ray J, as Brandy has no other siblings. There are no further shots taken, as Kanye sticks to the lyrics of the original song the rest of the way.

This of course all goes back to the mother of Kanye's daughter, Kim Kardashian. Ray J is Kim's ex-boyfriend, and is known for having made an infamous sex tape with her. Earlier this year, Ray J released a track called 'I Hit It First,' a blatant reference to his former flame. The intent was made more evident when the accompanying music video featured a leading lady that looked similar to Kardashian. Kanye has never addressed Ray J or this song until tonight.

The performance might have been overshadowed by the attack on Ray J, but it was a stellar performance nonetheless. Kanye was backed by The Roots and accompanied by the legendary Charlie Wilson. This combination worked to perfection. Meanwhile, Kanye exuded confidence throughout, aware of the fact that he had made a statement.

Kanye's performance tonight will definitely have everybody talking for the rest of the week. Check it out below.
