Kanye West is mad at Taylor Swift again. Only this time, he's throwing Justin Timberlake and Jay-Z under the bus too. Fortunately for all of us, Kanye West always has a microphone in his hand so we can hear him loud and clear.

Four years after Kanye grabbed the microphone from Swift at the 2009 MTV VMAs and uttered the infamous, "Imma let you finish" line, then proceeding to argue how Beyonce's Single Ladies should have taken home "Best Music Video of the Year," the soon to be Kardashian baby-daddy dissed the 24-year old songstress during an interlude for his song "Clique" on stage in London last weekend.

"Taylor Swift beat Beyonce at the Grammys? Beyonce be dancing in heels and s***,"

West's disapproval of Swift's art is well documented. What may have been more shocking was his critique of Justin Timberlake's "comeback" performance of his upcoming single "Suit & Tie" with Jay-Z at the 2013 Grammy Awards.

"I got love for Hov," West said of his longtime friend and music partner, "but I ain't f***ing with that 'Suit & Tie'."

West went on to criticize singers who sell out for fat paychecks from big corporations.

"Can I sell your drink for you please? So you can help me put on a better show."

Could this be a veiled reference to his friend, and Jay-Z's wife, Beyonce, having recently signed on with Pepsi for a $50 million endorsement deal?

While Timberlake and Jay-Z have yet to comment, it's bound to add a little juice to the duo's upcoming and highly anticipated Legends of the SummerTour.
