Scary!

Kris Jenner got quite the surprise when an obsessed fan waltzed into her home office in her Calabasas mansion on Tuesday afternoon, TMZ reports. Apparently, the unidentified man arrived in the middle of the day and posed as one of the crew setting up Christmas decorations at the momager's pad in order to get past the gated community security.

When the family matriarch came face-to-face with the intruder, she immediately realized he did not belong to the group of workers she had hired and called the cops, who arrived within minutes to arrest the man.

Law enforcement discovered he had taken a bus all the way from Texas to get there, and determined he needed to be placed on a psychiatric hold at a local hospital. The most terrifying part? Kim and her newborn son Saint were in the next room! What if this guy had a weapon?!

We can't believe it's that easy to slip into the Kardashian compound!
