Something is rotten in the state of Kardashian. A day after it was revealed that Khloe Kardashian was robbed of $250,000 in jewelry stored at a California house she recently sold, sources leaked that her big sis Kourtney was the victim of a $50,000 theft last month.

Someone with sticky fingers pocketed 50gs in cash from the eldest Kardashian sister's Calabasas home. The money was supposedly a fee from an appearance that was paid in cash (!!!). Um, maybe Kourt should have stopped by a bank to deposit the money?

The loot was supposedly stored in a safe place, but apparently, not safe enough, like an actual safe with a combo and a lock. Kourtney noticed the cash had been stolen a few days later.

The authorities are said to believe that the two thefts are related, and Kourtney herself also believes it was an inside job. Since both sisters deal with a lot of the same people, the thefts appear linked.

TMZ reports that cops will be speaking with those who had access to the homes of both reality show stars.
