Scary situation for Kris Jenner.

The 60-year-old momager came face to face with a trespasser on Tuesday, who entered her Malibu, California home after claiming to know her, a Malibu/Lost Hills Sheriff's Department spokesperson confirms to ET.

Although security let the man -- described as an out-of-state, black, male adult -- through, Kris quickly realized she did not know him, and she or someone in the house called 911. The man was not threatening anyone, and no arrests were made. He was, however, transported to a local hospital and placed on psychiatric hold.

Kim Kardashian has been staying with her newborn baby, Saint West, at Kris' residence since giving birth to her second child, and the two were reportedly home when the incident took place.

The man reportedly posed as a Christmas decorator to enter the home, which makes sense when you see the elaborate decorations Kris posted on Wednesday, writing, "It's beginning to look a lot like Christmas... Thank you @jeffleatham for making my house feel magical for my Grandchildren!!!! I am in awe!!! #beautiful #christmastime #stunning #obsessed #santa #besttreeever."
