Ellie Goulding and Lily Allen led tributes to Peaches Geldof on Monday.
The British TV presenter and fashion model died unexpectedly at the age of 25, leaving behind two young children.
And stars flooded Twitter after the news broke, sending her family their thoughts and prayers.
“Even if you think you’ve got it all figured out, some things still can’t be explained or understood. Two beautiful children. RIP Peaches,” Ellie wrote.
“My thoughts are with Peaches’ family at this awful time. I hope they get to grieve in peace. Peaches, rest in peace gorgeous girl,” Lily echoed.
Sharon Osbourne added that she was “devastated” by the news.
“…Sending condolences & respect to the Geldof family. It’s unimaginable what they must be going through right now,” she tweeted.
Alyssa Milano and Boy George also sent their condolences.
“Peaches! You beautiful thing. Rest with the angels. My thoughts and prayers go out to all that knew and loved you,” the actress wrote.
“Poor sweet Peaches Geldof. We spoke only a month ago and she looked like an angel. This is truly sad. Poor Bob! R.I.P,” Boy George added.
Peaches is survived by her husband of 19 months, Thomas Cohen, and their two sons, Astala Dylan Willow, 23 months, and Phaedra Bloom Forever, 11 months.
She also leaves behind her father, Boomtown Rats musician Sir Bob Geldof; the memory of her late mother, Paula Yates; sisters Fifi Trixibelle and Pixie and half-sister, Tiger Lily Hutchence Geldof.
Bob released a statement shortly after news broke of his daughter’s death, revealing that his family is “beyond pain”.
“She was the wildest, funniest, cleverest, wittiest and the most bonkers of all of us," he said.
"How is this possible that we will not see her again?"
“My beloved wife Peaches was adored by myself and her two sons," Thomas added in a statement.
"I shall bring them up with their mother in their hearts everyday. We shall love her forever."
Details surrounding Peaches’ death remain unclear.
BBC News reported emergency responders were unable to save her after police were called to do a welfare check at an address near Wrotham, Kent on Monday afternoon.
"At this stage, the death is being treated as unexplained and sudden," Kent Police said in a statement.
