This is the first time the rapper has performed tracks from his latest album release 4:44 and his first UK live performance in four years, since his Magna Carter World Tour.

To mirror the minimalist aesthetic of the album artwork, Jay Z took to the stage with what appeared to be an orange Jeff Koons balloon dog, which at times became a shade of blue.

So are the pair hinting at a future collaboration? In his 2013 song Picasso Baby Jay Z rapped: ''Oh what a feeling, f*** it I want a billion / Jeff Koons balloons, I just wanna blow up." In reference to Jay Z's V Fest staging, Koons' studio told Artnet News "Jeff has always been a fan.''

All this only begs the questions: was the balloon dog an original Koons? And are the creative duo planning a project?

If they did, it would be a lucrative one, as Jay Z's 4:44 went platinum in less than a week, whist back in 2013, Koons set a record as his Balloon Dog (Orange) sold for $58.4 million at Christie's, making it the highest price ever paid for a work by a living artist.
