Thanks to a video shared by David Ortiz on Instagram the night before Boston’s 4-3 ALDS-clinching win over the rival Yankees on Tuesday night, we now know, clearly, that rapper Cardi B is Boston Red Sox fan. 

She backs it up, too, noting that though she’s from Highbridge, “nine blocks from Yankee Stadium,” her father and grandfather also swore allegiance to Boston over the Yankees 

Looks like a whole family of traitors. 

Her and Big Papi should go get a room.
