Kanye West finally fires back at Ray J

It took Kanye five months to respond to Ray J. Five whole months, Kanye! What's happening to you? Lol. Five months after Ray J famously released a single called 'I Hit It First' that was aimed at Kanye West and K, Kany 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"

But why bother respond now? Especially while wearing a skirt...lol
