Scott Disick's LA mansion has been broken into while the reality star has been partying away in Cannes.

TMZ reports that a significant amount of money was stolen from his home, as well as jewellery and watches worth a sizable sum.

One of the watches reportedly cost $48,000 (€43,000), and a Rolex Yacht-Master II which is valued at $32,000 (€29,000) was taken as well.

While it is not yet known how much was robbed in total, law enforcement sources say it was "a significant amount of money."

However, the police source also claims that the thief was someone close to Scott as there were no signs of forced into his Hidden Hills home.
