Kanye West took a jab at Ray J during a surprise performance on "Late Night With Jimmy Fallon," MTV reports. The rapper finally responded to Ray J's jab at Kim Kardashian when he released a summer song called "I Hit It First."

West dropped by the late night talk show to perform his newest single "Bound 2" from his album "Yeezus." West changed the lyrics at the beginning of the song and rapped "Brandy's little sister lame, man, he know it now/When a real brother hold you down you supposed to drown."

In that one line West called Ray J a lame and girl. This was the first time West addressed the singer about the song. Over the summer Ray J had people talking when he released the single "I Hit It First."

He never really said whether the song was about his ex-girlfriend even though the lyrics - and the music video - hint that it is.

"She might move on to rappers and ballplayers but we all know I hit it first... I had her head going north and her a** going south but now baby chose to go West," Ray J sang.

In the video the "One Wish" singer featured a Kardashian look-a-like and recreated the infamous sex tape. During an interview on the Wendy Williams show, the R&B singer admitted in a roundabout way that he was singing about the "Keeping Up With the Kardashians" star.

"Are we still denying that it's not Kim Kardashian in the pixel?" Wendy Williams asks Ray J.

"Look, I never denied it. I never denied it. I just felt like in the promotional campaign to go so hard after you already know what the song is about... It was just too much," he said. "I just let the song speak for itself."
