Now they’ve got bad blood.

Taylor Swift is letting it be known loud and clear that she’s not going to stand for people claiming responsibility for making her famous, regardless of what Kanye West might say.

While picking up her award for Album of the Year, Swift seemingly shot a serious barb at West, who last week made headlines thanks to one of the tracks off new album The Life of Pablo, “Famous,”; which contains the lyrics: “I feel like me and Taylor might still have sex. Why? I made that b***h famous.”;

“As the first woman to win album of the year at the Grammys twice, I want to say to all the young women out there — there are going to be people along the way who are going to try to undercut your success or take credit for your accomplishments or your fame,”; said Swift in her speech, her voice cracking with emotion.

“But if you just focus on the work and you don’t let those people sidetrack you, someday when you get where you’re going, you’ll look around and you will know that it was you and the people who love you who put you there. And that will be greatest feeling in the world.”;

West has previously claimed that he told Swift about the lyric and she “gave her blessings,”; claiming on Twitter the idea for the lyric was “actually something Taylor came up with. She was having dinner with one of our friends who’s name I will keep out of this and she told him I can’t be mad at Kanye because he made me famous! #FACTS.”;
