Hilary Duff just learned a costly lesson about posting holiday snaps on social media.

On Wednesday, Hilary Duff posted a series of snapshots to Instagram. In one carefree video, she handstands, then dives of the edge of a picturesque pier. “CANADA,” reads the caption alongside it.

Later that day, thousands of kilometres away back in California, someone broke into the singer-turned-actor’s empty Beverley Hills mansion and robbed her.

According to TMZ, while Duff was “losing track of the days” (as she wrote in another post), a thief or thieves robbed the Younger star of hundreds of thousands of dollars worth of jewellery and valuables.

The full extent of the damage is reportedly not yet known as Duff and her family, including her five-year-old son Luca, are still believed to be abroad.

“This is a scary and upsetting situation for anyone to go through, but Hilary is thankful that her family, her staff, her home and her pets are all safe,” the 29-year-old’s rep told Us Weekly.

“That said, she has a significant security team in place that will work with the authorities on this incident and handle security measures moving forward.”

While authorities have not been confirmed that Duff’s conspicuous absence played a role in the robbery, parallels are being drawn between the crime and the terrifying hold-up of Kim Kardashian in a Paris last October.

The reality television star was robbed of millions of dollars worth of jewellery by armed thieves who stormed her hotel room. Local authorities later suggested that the mother of two’s social media posts sparked the crime, as they showed off the jewels she was wearing at various Fashion Week events in the French capital.
