Talk about a random spur-of-the-moment vacation!

On Wednesday morning the Kardashians (well, most of them -- we spotted Khloe, Kim, Nori, Kourtney, Penelope, Mason, Reign and Scott Disick) hopped on a private jet, and X17online can report exclusively that the group was headed to Montana, where they're going to spend a few days in Yellowstone National Park! Not your typical family getaway, but it will certainly be quite exciting!

Kim carried Nori while Kourt carried baby Reign, and Scott was in charge of Mason and Penelope. Scott has to make an appearance in Las Vegas on Saturday, so it won't be a very long trip, but seeing as this will be appearing on an upcoming episode of Keeping Up With The Kardashians, just a few good hours of footage is all that really matters, right? Sigh...
