Walking alongside Kim Kardashian and North West ... Kourt's 7-year-old son gave paps the ol' "no pictures" on his way to see his mom exchange vows. Evidently, the photographers didn't scatter fast enough, because Reign loudly added ... "Give us a break!"
It's hilarious ... while he's the youngest of the 3 walking to the wedding, he's the one to speak up and give the paparazzi a piece of his mind.
As you know, Sunday marked Kourtney and Travis' 3rd time tying the knot.
They went all out ... exchanging vows in front of family and friends at the seaside compound of Domenico Dolce and Stefano Gabbana in Portofino, Italy.
