Fifi Geldolf slammed critics of her late sister Peaches on Instagram on Wednesday after a coroner ruled her death was caused by a heroin overdose.
The 31-year-old posted an angry message to the social-networking site just hours after prolific Twitter user Katie Hopkins shared her own controversial views on Peaches' death following the public details of her inquest.

Reacting to the negative backlash, the eldest daughter of musician Bob Geldof posted a photo to her Instagram page, reading: "Don't keep calm and f*** this. F*** that. F*** you. F*** off."
Fifi summed up her feelings in a message accompanying the image, writing: "Sums it up nicely about how I'm feeling about the viciousness today... Maybe now she'll be allowed to RIP."
On Wednesday former Apprentice star Katie Hopkins left scathing comments on Twitter about Peaches following the circulation of a headline describing the mother-of-two as a "fallen angel".

The 39-year-old questioned whether the tables would be turned if she also died in the company of her young child from an overdose.
"Let's turn the tables. It was me that took an overdose whilst caring for my 11 month old. Would I be a fallen angel too?" Katie asked.
Peaches' fatal syringe was in a box by the bed - along with some sweets. She was taking care of her baby son after all.

Question have been raised whether Peaches was fit to look after her two sons, Astala and Phaedra, after a court heard that she went back to using heroin in February this year after receiving treatment for her addiction for two years.
Husband Thomas Cohen, who gave evidence at the inquest in Gravesend Town Hall, Kent, admitted he knew his wife had relapsed after finding suspicious text messages on her phone.
