G.O.O.D. Music founder and frontrunner Kanye West has been out and about in NYC this weekend participating in New York Fashion Week, but he didn’t leave the Big Apple without stopping by Late Night With Jimmy Fallon.

At the start of soulful Yeezus record “Bound 2,” ‘Ye threw a quick jab at Ray J: “Brandy’s little sister lame and he know it now.”

The lyrical diss comes as a result of Ray J’s flagrant song “I Hit It First,” which directs shots at his ex-flame and Yeezy’s current wifey, Kim Kardashian.
