Kanye West, who has just become a father to Kim Kardashian's newborn daughter North West, launched into a Twitter tirade after his music video for Black Skinhead was leaked online.
Kanye vented his frustration and anger, calling the incident "heartbreaking".
"Me and Nick Knight have been working on this video for 5 months and for creatives it's heartbreaking when something like this happens," tweeted the rapper.

Kanye had been collaborating with British fashion photographer, Nick Knight, who has worked with Lady Gaga on her hit video Born This Way.
He went on to announce that the leaked clip was not the official or finished version, and lashed out at the unknown culprit with an expletive in another post.
"And to who ever leaked the video… **** YOU!" he tweeted.
The Stronger rapper gave a more polite request to the websites that had already posted the unapproved video, tweeting, "So any website that may have the unapproved/unfinished ruff. I ask you to please take it down."
The leaked version, which has now been taken down, showed clips of the rapper dancing around topless and morphing into creatures, and also featured barking dogs and zombies.
The finished version of Black Skinhead, the first single to be taken from Kanye's sixth studio album Yeezus, will be ready within the week, the rapper announced.
