If Kanye West's girlfriend Kim Kardashian has an unhealthy obsession with Duchess of Cambridge Kate Middleton, the rapper seems to have a Jay Z fixation.

Kanye and Jay Z have collaborated on a number of projects, and it is no secret that Kanye considers the rapper a big brother. Reports have it that Kanye even wanted his baby mama Kim to get close to Beyonce so that all of them could be one big family. And while Kim had been working towards it, Kanye did not expect the entry of Justin Timberlake with his latest "Suit & Tie," or the "Sexy Back" singer's collaboration with Jay Z. And much to Kanye's dismay, Justin and wife Jessica Biel sat next to Jay Z and Beyonce during the Grammys, a function that the "Mercy" singer decided to skip.

To make matters worse, Jay Z and Timberlake have even announced that they are hitting the road together for their "Legends of the Summer" tour, which has not gone down well with Kanye.

But instead of trying to bridge the apparent distance that has come between the "Watch The Throne" partners, Kanye decided to vent out his frustration through music. Last month in London, Kanye went on a free-style rant slamming Justin with the words, "I got love for Hov, but I ain't f--kin' with that 'Suit & Tie.'"

Watch the video below:

While the "Suit & Tie" singers stayed mum when Kanye's childish antics were first brought to light, Justin decided to give it back during his appearance on Saturday Night Live. Justin tweaked the lyrics of "Suit & Tie" from "Aww, s**t so sick, got a hit and picked up a habit" to "my hit's so sick got rappers acting dramatic."

Though not the harshest of words, this is a subtle diss to Kanye, who undoubtedly will be coming out with something more dramatic in the coming days.

In the meantime, a number of publications have labeled Kanye's behavior childish and immature. "At this stage of his career, Kanye West is living vicariously through Kim's womb. There's no other way to explain his increasingly childish and erratic behavior," the Shadow League said. Fingers are also being pointed towards Kim, who has been largely blamed for Kanye's losing his hold in the music industry.
