Say what?! Kanye West performed at the X Games in Austin, Texas over the weekend, and according to a number of fans, the rapper removed pal/collaborator Jay Z's name from no less than three songs during his set! And not only that, but there's video of it too!

Kanye didn't say Jay's name when he performed "Cold," and when he sang "Blood on the Leaves," he changed the lyric, "He ain’t with you, he with Beyonce, you need to stop actin’ lazy" to "You need to stop actin' crazy." He ALSO omitted Jay Z's name in his old hit "Touch the Sky." Meow, Yeezy!

As you know, Beyonce and Jay Z bailed on Kanye and Kim Kardashian's wedding last month in Florence, Italy, and though Kim's mom Kris Jenner claimed that she figured the duo were busy with work, they were posting vacation pictures from the Hamptons. (Translation: Bey and Jay wanted nothing to do with Kim's D list nuptials -- and they weren't the only ones!) Kim was reportedly furious that the superstar couple bailed on her big day, and it seems like Kanye might be bitter about it as well!

And this wouldn't be the first time the rappers have butted heads. Back in 2011, the New York Post reported that they were "barely speaking to each other" after disagreeing on the details of their Watch the Throne tour.
