Four days ago, the reality TV star posted a photograph of a huge ring on her left hand captioned with three diamond emojis.
Kim Kardashian West was robbed at gunpoint of millions of pounds worth of jewellery after making herself a target by flaunting her lavish lifestyle on social media, police have said.
The 35-year-old reality TV star reportedly had a gun held to her head before she was tied up and locked in the bathroom of a luxury residence in the French capital where she was staying during Paris fashion week.
She was "badly shaken but physically unharmed," a spokeswoman said.
Five masked and armed men were involved in the raid and escaped with a jewellery box containing a ring worth €4m (£3.5m), as well as other valuables worth between €5m and €6m (£4.4m - £5.2m).
Four days ago, Kardashian West posted a photograph of a huge diamond ring on her left hand captioned with three diamond emojis.
Johanna Primevert, chief spokeswoman for the Paris police department, said: "This is the result of people who obviously posed as policemen and who assaulted Ms Kardashian in a private hotel in her room by threat of a weapon.
"This kind of incident is extremely rare in Paris. This is a star who is famous worldwide.
"Do not confuse what happened to Ms Kardashian - and probably was the result of an organised team who had planned their action - with the assault of a tourist in front of Notre Dame (cathedral) or another tourist spot in Paris."
She said the losses were estimated at several million euros, adding: "Clearly when you have a star like Kim Kardashian who has, I think, more than 48 million followers on Twitter... I think this could have happened abroad just as easily as in Paris.
"It was really the celebrity who was targeted, with possessions that had been seen and noticed via social media, and it was these goods that the attackers targeted."
Kardashian West left Paris on a private jet just hours after the robbery which took place at around 3am local time on Monday.
She was met by her husband, rapper Kanye West, who cut short a concert at Meadows Festival in Queens, New York, following the incident.
The 39-year-old has rescheduled two US tour dates in the wake of the robbery, with promoter LiveNation citing "family concerns" as the reason.
The celebrity couple have not spoken about the robbery - either in public or on social media.
