Peaches Geldof’s sister Fifi hits out at critics: ‘F**k this. F**k that. F**k you. F**k off’

This week saw the sad conclusion of Peaches Geldof's inquest, which found that the socialite had died from a massive heroin overdose with her one-year-old son Phaedra in the house.

People quickly took to social media to spout their views on her death, including some who targeted Peaches' sister Fifi Geldof to tell her exactly what they thought of her sibling's tragic end. Nice.

The 31-year-old wasn't going to take that lying down, so wrote a series of messages blasting the trolls. "Don't keep calm and fk this. Fk that. Fk you. Fk off," said one snap, which she captioned, "Sums it up nicely about how I'm feeling about the viciousness today. Maybe now she'll be allowed to RIP".

When one reader suggested Peaches had been "selfish" to take drugs with a baby in the house, Fifi let rip. "You've no idea what you're talking about quite frankly. Yet another who has bought into the bullst," she told one. "I'd appreciate you getting the fk off my page with stuff like that on today of all days," she wrote to another.

Luckily there were some supportive users sending her messages of sympathy, which she said she appreciated. "Thanks for your beautiful words of love and support for myself and Peaches. I appreciate it more than ever today," Fifi added.
