The 'Loyal' hitmaker - who goes by the moniker Konfuzed in the art world - has collaborated with photographer Karen Bystedt to produce a collage of the legendary, late US artist Andy Warhol.

Karen has listed the artwork, called the Triple Andy Discount, on online auction site eBay with a starting bid of $500,000, and some of the proceeds will go to the hurricane relief efforts in Puerto Rico.

The listing stated: "A portion of the proceeds of the sale will be contributed to hurricane-maria-pr-relief-effort at Go Fund Me. (sic)"

The piece features two paintings Chris has done of the legendary artist either side of an iconic photograph of Andy taken by Karen.

The listing reads: "This original art piece titled "Triple Andy Discount" was painted by Chris Brown on top of Bystedt's photograph of Andy Warhol, in Los Angeles in November 2015, for a private show at Hyde Lounge and is only now being released for sale.

"It is a rare departure from his monsters theme.(sic)"

At the time of writing the artwork, which is 44-inches in height and width, hasn't received any bids.

Chris and Karen originally collaborated on a hat-trick of mixed media art pieces in 2014 which were exhibited at her show Andy Goes Street in Culver City, and the trio sold.

Bidding for the artwork concludes in the early hours of Tuesday morning (14.11.17).

Chris has had a busy year and he revealed the results of which late last month when he dropped a 45-song album, his eighth studio LP, 'Heartbreak on a Full Moon'.

It'll take fans almost three hours to listen to all of it as he's piled on the huge number of tracks - the equivalent of around four albums - and pulled in the likes of Usher, R. Kelly, Gucci Mane, Lil Yachty and Jhene Aiko for collaborations.
