Taylor Swift is upset Kanye West jumped onstage at the Staples Center in Los Angeles Sunday night after Beck won the Album of the Year award at the 2015 Grammys, a source told Hollywood Life. West thought Beyoncé should have won the accolade, but instead of interrupting Beck’s speech, he just jumped off the stage and sat down.

Swift, 25, knows what it feels like to have the rapper infringe on an award-winning moment. West infamously stole the microphone from her during the 2009 MTV Music Awards to say, “Yo, Taylor. I'm really happy for you. I'mma let you finish, but Beyonce had one of the best videos of all time.” Swift, then 19, was left with her mouth open, unsure of how to bounce back.

After he almost did the same thing to Beck, an insider told Hollywood Life: “Taylor is disappointed that Kanye would go down this road again. Taylor feels Beck’s achievements and his experience are being tainted because of Kanye and his massive ego. She thinks Kanye really is a nice guy deep down and doesn’t do these things maliciously but he needs to stop putting his ego above everyone else. It’s just selfish!”

Even though the rapper, 38, said Beck should “respect artistry” and give his Grammy to Beyoncé, Beck, 44, told Us Weekly West is “genius.” "I thought she was going to win. Come on, she's Beyoncé! … You can't please everybody, man. I still love [West] and think he's genius. I aspire to do what he does."

As for Beyoncé, she has not issued a public comment. But the shocked look on her face when West jumped up to the stage quickly went viral on Vine. Check out the awkward moment below:
