Kanye West has remained quiet through all of Ray J’s attempts at publicity. But now the rapper has finally spoken out through music. During an appearance as the musical guest on Late Night with Jimmy Fallon yesterday, Yeezy changed the lyrics of his song “Bound 2” in order to slam Ray J. West’s musical diss was likely a response to Ray J’s song “I Hit It First,” which directly references his sex tape and former relationship with Kardashian.

During the Fallon performance, West rapped: "Brandy’s little sister lame man he know it now / When a real brother hold you down, you ‘sposed to drown." Last April, Ray J released “I Hit It First” and even shot a video with a fake Kardashian look-alike, in addition to releasing cover art that appeared to be a pixelated photo of his former girlfriend. Kardashian was reportedly angry about the song, but chose not to comment on it.

"She might move on to rappers and ball players / But we all know I hit it first," Ray J rapped on the track. "I had her head going north and her a*s going south / But now baby chose to go West. / No matter where she goes or who she knows / She still belongs in my bed." Ray J made light of the track by tweeting it "wasn't that serious" and said people are reading into it too deeply. Sources close to West said he refused to comment initially because he didn’t want to give Brandy’s brother any free press.

"Kanye don’t condone broke a*s, jealous [guys] who be trying to bite off he and Kim’s fame just to stay, wait, just to become relevant. Kanye West and Kim Kardashian will not give Ray J attention," a source said to MediaTakeout.

And while West has continued to remain one of the most successful performers in the world, Ray J’s music career has floundered. His Kardashian track only debuted at No. 51 on the Billboard Hot 100 and he hasn’t released a new album in over four years. He currently co-stars on TV One sitcom The Ricky Smiley Show, which was picked up for a second season this summer, and recently hosted Bad Girls All-Star Battle on Oxygen.
