Performance artist Marina Abramović has accused Jay Z of "completely using" her when the pair collaborated on the rapper's 2013 Picasso Baby: A Performance Art Film video.

The video saw Beyonce's hubby film himself rapping for an incredible six hours in Pace gallery in New York, two years ago.

It was inspired by Abramović's work The Artist Is Present, which she had first performed three years before at the Museum of Modern Art in New York.

In it, the artist sat silent on a chair for 736 hours, and Jay's video saw him rap to celebrities including Jim Jarmusch and Adam Driver and fans in his own take on it.

However Abramović says she only agreed for Jay to include her work in his video, if in return, he would 'help her institute' - which she now claims "he didn't".

“The day before, he came to my office and I gave him an entire PowerPoint presentation and said: OK, you can help me, because I really need help to build this thing,” she told Spike magazine.

“Then he just completely used me. And that wasn’t fair. This is very different from Lady Gaga, for example, who has done great work for me. Just by having 45 million followers, she brought all these young kids into my public.”

However she doesn't regret doing it - she said she'd simply think harder before repeating the experience.

“In the end it was only a one-way transaction. I will never do it again, that I can say. Never,” she added.

“I was really naive in this kind of world. It was really new to me, and I had no idea that this would happen. It’s so cruel, it’s incredible. I will stay away from it for sure.”

Marina Abramovic Institute has since apologised "to Jay Z (and Marina Abramovic)" for saying he didn’t donate for Picasso Baby.

They tweeted: "Marina Abramovic was not informed of Shawn 'Jay Z' Carter's donation from two years ago when she recently did an interview with Spike magazine in Brazil. We are sincerely sorry to both Marina Abramovic and Shawn 'Jay Z' Carter for this, and since then we have taken to appropriate actions to reconcile the matter."

We have contacted Jay's reps for comment.
