There's been a second Kardashian home invasion, this time at Kourtney Kardashian and boyfriend Scott Disick's pad, and cops believe it's connected to the robbery at Khloe Kardashian's house last month.

A whopping $50,000 in cash was stolen from Kourtney's Calabasas, Calif., home around the same time that more than $250,000 worth of jewelry was taken from Khloe and ex Lamar Odom's house.

The timing and the sisters' many mutual connections have led cops to connect the incidents, and they are now looking at people who had access to both gals' homes, TMZ reported.

Kourt's $50K came from an appearance she was paid for in cash. She had stored the dough in a "safe" place, according to TMZ, and had only noticed it was missing when she went to deposit it.
