Inside the Chris Pratt vs. Chris Evans Twitter Feud Over Super Bowl

"You are not my friend, you are my enemy," Evans told Pratt.

Evans, a Pats fans, opened the Twitter battle, first reaching out to Pratt, a loyal Seahawks supporter.

"Well, well, well @prattprattpratt, looks like our teams are going into battle. For the next 2 weeks, you are not my friend, you are my enemy," Evans wrote on Monday.

Then Evans came back, "@prattprattpratt them's fightin words. Stakes? #whatisaseahawkanyway #somethingtombradyhunts."
