Kris Jenner -- Say Hello To My Little Friend (PHOTO)

Don't mess with Kris Jenner in Paris.

The Kardashian matriarch is all over Fashion Week ... although it's hard to spot her in the considerable shadow of her mammoth new bodyguard, who is a dead ringer for a modern day Thor.

Sure, Kris is only 5'6" ... but her slab of beef-for-hire looks to be at least THREE heads taller than her. Warning: Approach the momager with extreme care.

King Kong (and the Eiffel Tower, for that matter) ain't got nothing on him.
