Kanye West: 'Taylor Swift's not cool any more'

Kanye West and Taylor Swift's feud has reached a new high after the rapper lashed out at the Blank Space singer during a nightclub appearance on Tuesday night (23Feb16).

The musicians have been at loggerheads since Kanye debuted a new track, Famous, at his New York Fashion Week show earlier this month (Feb16). The song features a line about the rapper sleeping with the 26-year-old, and the claim he made her famous by storming the stage to protest her 2009 MTV Video Music Awards win.

Taylor shot back at West with a thinly veiled dig at him while accepting Album of the Year at last week's (ends19Feb16) Grammy Awards, and now Kanye has lashed out once again.

"I said, ‘How you feel about this line, Taylor?'” Kanye said at Los Angeles’ 1OAK club before quoting part of the song. “I was like, ‘Taylor, I feel like me and you might still have sex’. She said, ‘Ooh, Kanye, I like that line'. Then she won her award and said something completely different. She’s not cool no more.

"She had two seconds of being cool - and she f**ked it up!"

Taylor's representative previously dismissed Kanye's claims he had approached the singer about his provocative lyric, insisting Swift had no knowledge of the song and she had not given her blessing for him to poke fun at her.

At the Grammys, Taylor took her moment in the spotlight to urge young women not be sidetracked by those who are not out to support them, and many fans and critics believed that was a dig at Kanye.

“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," she said.

The pair's history goes back to 2009, and Kanye's unforgettable stage invasion at the MTV Video Music Awards, when he grabbed the mic from a stunned Taylor and protested her first ever VMA win for Female Video of the Year, arguing his pal Beyonce should have won the prize.

The two stars appeared to have put the feud behind them last year (15), when Taylor presented the rap star with the Video Vanguard Award at the 2015 VMAs.
