And then there’s this:

British bad boy rocker Pete Doherty is auctioning off some of his possessions and artwork this Friday. Included in the sale is “Ladylike,” a mixed media painting on which he says the late Amy Winehouse drew a self-portrait and smeared it with her own blood.

Yes, a devotee of Winehouse, who died from alcohol poisoning last summer, can now own something purportedly created with one of her bodily fluids. It does not get anymore intense than this.

If, for some reason, you are interested in bidding on “Ladylike,” take pause: Mitch Winehouse, the singer’s father who runs the foundation set up in her honor, has cast doubt on the authenticity of the painting.

The Independent reports that the piece, part of an auction conducted by the Cob Gallery in London, is expected to fetch between £50,000 and £80,000.

An undisclosed percentage of the sale will benefit the Amy Winehouse Foundation, according to the Independent.

Mitch Winehouse strongly suggests he doesn’t believe it.

“Do you believe that Amy painted that picture in her blood? Absolute rubbish,” he tweeted earlier this week. Request for elaboration on this tweet from his publicist has not been returned.

Doherty remembered the night he says he and his friend created the painting to the Independent. “Amy was on the phone to her dad when she did that [painting],” Doherty told the Independent. “She said, 'Dad, I'm with Pete and he's making me draw with my blood!' He didn't like me much, her dad.”
