Danny Amendola is fighting back after his ex-girlfriend, Olivia Culpo, was spotted on a vacation with Panthers running back Christian McCaffrey.  The Lions receiver posted a picture on Friday of himself with McCaffrey’s ex-girlfriend, Brooke Pettet.

This back-and-forth is becoming one of the more entertaining in sports.  Amendola just took things to another level.  In order for McCaffrey to fire back, he might have to start hanging out with Amendola’s mom or sister (if he has one).
