Johnny Depp on Thursday sold a collection of prints he created of Hollywood and rock icons for around £3 million ( €3.57 million) via a UK gallery chain.

The 59-year-old Pirates of the Caribbean star has spent millions on a bitter legal battle with his ex-wife, the 36-year-old actress Amber Heard.

Depp wrote on Instagram on Thursday morning that the prints were going on sale online at Castle Fine Art, which runs a network of UK galleries.

The art retailer posted a photo of Depp working on a portrait of singer Bob Dylan. 

It said that the collection of prints called Friends & Heroes was “a testament to those he has known well and others who have inspired him as a person”.

The gallery quoted Depp as saying: “My paintings surround my life, but I kept them to myself and limited myself. No one should ever limit themselves.”

The works depict Dylan, the late actress Elizabeth Taylor, actor Al Pacino and Rolling Stone Keith Richards.

The gallery chain later posted a tweet saying that “Johnny Depp broke the internet” and its website had crashed due to demand.

All the prints were marked as “out of stock” by Thursday evening. There were 780 pieces of art.

Buyers paid £14,950 for a set of all four framed prints or £3,950 for a single print. 

Depp in June won an award of $10 million in a defamation case against Heard in the United States, while she won $2 million in damages after countersuing. 

Heard is appealing against the verdict of the jury trial, which was live-streamed to millions and featured lurid and intimate details about the former couple's private lives.

Depp previously lost a libel case against the British tabloid The Sun in London in 2020 for calling him a “wife-beater”.

In another creative venture, the actor this month released an album with English rocker Jeff Beck.

The record has been poorly reviewed by critics but broke into the top 40 in the UK.
