Just in: PATRICK & BRITANNY MAHOMES TROLLED BY FANS ON VACATION … Raider Nation Out In Cabo!!!

Patrick and Brittany Mahomes might be on vacation, but the trolls seem to find them regardless … with some hardcore Raiders fans giving them guff as they left a restaurant.

TMZ obtained video of the pair grabbing a bite at Rosa Negra — a luxury Latin restaurant in Cabo San Lucas, Mexico — Thursday night, and it looked like one hot date night for the couple, sans any kids.

Eyewitnesses say the couple hung out for about two hours before dipping out … and, that’s when they got heckled by some fans of an opposing team … with some goons booing and hissing them, not to mention shouting “RAIDERS” to Patty and Brit as they bounced.

It’s all clearly in good fun here — though pretty bold of LV fans to troll Mahomes to his face. But, we doubt he’s sweating it … remember, Pat won a Super Bowl on Raiders’ home turf about two months ago — so, ya gotta think he’s got a leg up on Las Vegas these days.

BTW … even though the couple’s enjoying their vacation, it doesn’t mean they’ve totally forgotten their friends. Brittany posted a message in support of her new bestie Taylor Swift after she dropped her ‘Tortured Poets’ album.
