The director of Taylor Swift's new video has taken aim at Yahoo Music bosses for posting the Blank Space promo online prematurely.

The official music video appeared on Yahoo - but it was not planned.

The promo was quickly taken down, and director Joseph Kahn has since hit social media to explain the screw up.

He writes, "Yup. Yahoo effed up. Wait to see the Blank Space video. Let Taylor introduce it herself. It'll be worth it."

Swift, who recently pulled her new album from popular streaming site Spotify, has since posted the official video, in which she appears to be living the high life with model Sean O'Pry in a stately home, riding horses, bicycles and dancing in a grand ballroom.

The promo takes a dark turn as the singer then throws flower pots, brandishes a butcher's knife and destroys paintings of her lover.

Kahn, who also directed Britney Spears' Toxic video, says, "She (Swift) is truly an entertainer. To be able to invest herself so fully into such a villainous character shows how much of a great entertainer she is."
