In a new Keeping Up With the Kardashians clip that was released ahead of Sunday night's episode, Kim Kardashian sits down with her sisters Khloe and Kourtney and speculates on the jewelry heist that took place in Paris last October.

Kim believes she was being watched by a group of men her entire trip, and her revealing Snapchat -- in which she documents Kourtney's exit from the building -- tipped off her stalkers to make a break for her private Parisian residence.

“What I think happened now, after thinking about it so much, is that there was probably a group of guys that were following us the entire trip,” Kim says to Kourtney and Khloe. “I was Snapchatting that I was home and that everyone was going out. So I think they knew Pascal was out with Kourtney and I was by myself. They had to of known we were leaving that day. They just had this window of opportunity and they just went for it.”

In October, news broke that Kim was tied up inside a bathroom while thieves dressed as police officers stole jewelry worth more than $10 million. TMZ reported in January that French police have since nabbed 17 people in connection to the robbery and hauled them into multiple police stations.
