Swift began her acceptance speech by thanking her fans for the past decade and her 1989 collaborators, from Ryan Tedder to Jack Antonoff, before firing back at the 38-year-old rapper on music's biggest night.
"And as the first woman to win Album of the Year twice, I want to say to all the young women out there, there are going to be people along the way who try to undercut your success or take credit for your accomplishments and your fame," she said.
"But if you just focus on the work and you don't let those people sidetrack you, some day 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 the greatest feeling in the world," Swift continued.
"I feel like me and Taylor might still have sex / Why? I made that b***h famous," he raps on the track from The Life of Pablo. Swift's younger brother, Austin, immediately responded to the diss by throwing out his pair of Yeezy sneakers.
According to Swift's publicist, the singer warned West about the "misogynistic message" that "Famous" sent. However, West claims he received Swift's "blessings" prior to the song's debut. Judging by Swift's reaction on the GRAMMY stage in arguably one of the biggest moments of her career, she was none too happy.
Earlier in the evening, Swift opened the GRAMMYs with a performance of her newest single, "Out of the Woods," and at the time refrained from addressing the West drama. It was only a matter of time before Swift would take the rapper to task.
