Chris Evans — best known as Captain America in the recent Avengers movies — took to Twitter recently teasing Chris Pratt — Star Lord from Guardians of the Galaxy –– about the upcoming Patriots vs. Seahawks Superbowl game.

Side bar: Can we just take a minute to appreciate the fact that Chris Evans roots for the Patriots. I mean, could he actually be a more perfect Captain America?!

Evans tweets to Pratt, saying, “For the next 2 weeks, you are not my friend, you are my enemy.”

After a small exchange, a bet is offically made. If the Seahawks win, Evans is to make an appreance as Captain America at the Seattle Children’s Hospital. Likewise, if the Patriots win, Pratt will dress as Star Lord and go to Christopher’s Haven, a pediatric cancer nonprofit in Boston.

Personally, I wouldn’t be surprised to see both men hold up their end of the deal regardless of the results next Sunday.

Until then, I look forward to more charitable trash-talk from these two.
