Taylor Swift has hit back at Kanye West’s claims that he “made her famous” in a purposeful and defiant Grammys speech.

After picking up the award for Album of the Year at the ceremony last night, the 1989 singer threw some subtle shade at the rapper – announcing that she wasn’t going to let anyone “undercut” her success.

“I want to say to all the young women out there: there are going to be people along the way who will try to undercut your success, or take credit for your accomplishments or your fame,” Swift said to the crowd. “But if you just focus on the work and you don’t let those people sidetrack you … 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.”

The retaliation comes after Yeezy controversially called out Swift on his Life Of Pablo track “Famous”. Addressing his infamous interruption of the singer at the 2009 VMAs, the rapper boldly implied that he was one of the sole reasons for her success. “I feel like me and Taylor might still have sex,” he asserts on the track. “Why? I made that bitch famous.”

West has since dismissed claims that the lyrics are disrespectful to Swift – even claiming on Twitter that she had already heard the track and given her approval. “I’ve not dissed Taylor Swift and I’ve never dissed her,” he wrote last week. “I called Taylor and had a hour long convo (sic) with her about the line and she thought it was funny and gave her blessings… I’m not even gone (sic) take credit for the idea…it’s actually something Taylor came up with…”

However, a representative for Swift has since refuted these ideas, adding that the “Out of the Woods” singer was worried about the overbearing misogyny of the track. “Kanye did not call for approval, but to ask Taylor to release his single ‘Famous’ on her Twitter account,” said the spokesperson in a statement. “She declined and cautioned him about releasing a song with such a strong misogynistic message. Taylor was never aware of the actual lyric ‘I made that bitch famous.’”

Yeah. Clearly not. Watch Swift’s speech in full above.
