You knew it would happen sooner or later and the time has finally come for Kanye West to take a stand about his baby mama, Kim Kardashian.

While Ray-J may have ‘hit it first,’ (watch ‘I Hit It First’ (official video), it was Yeezy who was the first to ‘knock it up’! 😆

At any rate, we no longer have to wonder what Kanye thinks of Ray J’s Kim Kardashian diss track because he decided to respond during a surprise performance of his song “Bound 2” on “Late Night With Jimmy Fallon” last night (September 9, 2013).

West altered the song’s opening lyric to attack the R&B singer/reality TV star, rapping:

Brandy’s little sister lame and he know it now, when a real brother hold you down, you supposed to drown.

(The original lyric is, “All them other n-ggas lame and you know it now, when a n-gga hold you down, you supposed to drown.”)

West didn’t mention Ray J by name, but there is no denying that the lyrics are about him. West instead chose to refer to the Ray J as the younger sibling of Grammy-winning singer and actress Brandy, giving her the shine instead.

Welp! Baby mama’s are forever… but then again, so are sex tapes!

What did you think of Kanye’s ‘diss’ of ‘Brandy’s lil brother‘ sister? 😆
