Kourtney Kardashian has had $50,000 stolen from her house.

Police reportedly believe the theft last month could be linked to a recent robbery involving her sister Khloe, who discovered $250,000 worth of jewellery had gone missing from her home in Tarzan, Los Angeles on Monday night (03.03.14).

According to TMZ, the money was stolen from Kourtney's Calabasas home after she had been paid cash in hand from an appearance gig and although the money was left in a safe place, the 34-year-old reality star was shocked to discover it missing a few days later.

Now Kourtney and Khloe, 29, are said to be suspecting both heists could be an inside job, as they along with their sister Kim Kardashian work with numerous people across 'Keeping Up With The Kardashians' , DASH clothing stores and other lucrative endorsements.

It's thought authorities will launch an investigation into which people had access to Kourtney and Khloe's homes at the time of the burglaries.

Meanwhile, it's been revealed the lavish mansion the Kardashian-Jenner family currently use for exterior shots on their reality show is for sale and the buyers have the right to pull the images from appearing.

The seven-bedroom home isn't actually lived in by the family but matriarch Kris Jenner didn't want to show the outside of their real house -located 20 miles away - for security reasons.
