C.J. Gardner-Johnson's feud with Travis Kelce and Taylor Swift is still raging on ... he's currently out firing more shots at the duo with his wardrobe at the Eagles' Super Bowl parade.
Check out the Philadelphia star's 'fit Friday ... he's got on a black and green hoodie that reads, "Swifties Can LIX My Balls."
He's proudly showing it off, too, broadcasting it live on his IG page ... while flashing it to fans who are lining Philadelphia streets to cheer on the new NFL champs.
