Lest we forget ... until Jordyn Woods hooked up with Khloe Kardashian's baby daddy, not many people even knew who the young lady whose claim to fame was being Kylie Jenner's bestie was!

But post-Tristan Thompson sleepover, post-Red Table Talk fallout, post-Kylie kicking her BFF to the curb, Jordyn Woods has apparently become famous.

She was shopping with her mom at luxury plumbing retailer Waterworks, on Tuesday, and you won't BELIEVE the gang of photographers, videographers, fans, Waterworks staff, and random passers by who got caught up the the Jordy chaos! People were legit livestreaming her exit from the store, trying to get selfies with the famous jezebel ... and why?!

Well if nothing else, it makes for great video -- watch!
