Listen to Kanye West on iHeartRadio | Listen to Ray J on iHeartRadio

(TMZ) - Reminding the planet that he "hit it first" wasn't enough ... 'cause Ray J went after Kanye West again last night ... and TMZ has the footage. 

According to TMZ, Kim Kardashian's sex tape partner was leaving Tru in Hollywood last night when he started mocking K's airport meltdown ... which is interesting considering Ray recently released a song bragging about banging KK way before Kanye came into the picture. 

Kanye hasn't really acknowledged Ray J's attempt at a beef yet. Think this will get his attention?
