Taylor Swift dissed Kanye during her acceptance speech at the Grammy Awards.
She's the first woman to win album of the year twice and said it was for "all the young women out there".
She said: "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."
Her speech appears to be in response to Kanye West's lyric from his new album where he claims to have made Taylor Swift famous.
And the internet has had a field day at Taylor's diss with Gifs predicting how Kanye will respond.
It all comes from a line from Famous on Kanye's new album: The Life of Pablo.
He raps: "I feel like me and Taylor might still have sex/Why? I made [her] famous."
And he claims to have had her blessing for the line as she "thought it was funny".
It refers to the MTV VMAs in 2009 when Kanye West interrupted Taylor Swift's acceptance speech.
He got up on stage while she was giving her speech after winning best female video for You Belong With Me.
Kanye thought that it should have gone to Beyonce's Single Ladies instead.
