What IS it with the Kardashian girls and their jewelry getting stolen?!

Kendall Jenner is the latest victim of crime against her bling, after half-sis Kim was robbed of considerably more rocks last October in Paris. Kendall's robbers got away with only $200K worth of gold and diamonds -- but that's still significant!

Today investigators were at the young model's Hollywood Hills home investigating and questioning the starlet. Kylie stopped by to give her sister some moral support and another friend was there to help Kendall get through the afternoon and to offer some company, as we can imagine she doesn't want to be alone in her big house right now. Hope she's got good insurance! And even better security cameras!
