Kanye West Disses Ray J During Fallon Performance!

So this is a response to Ray Jays 'I Hit It First' aimed at Kanye West and Kim Kardashian. Kanye finally has fired back! In a performance of his single Bound 2 on Jimmy Fallon last night Kanye West changed the first line of the song and sang, 

"Brandy little sister lame and he know it now. When a real brother hold you down, you ‘sposed to drown"

Ade Kanye, Question please, why wait this long? Why even bother?
