Bradley Cooper‘s going to be all nerves when his Philadelphia Eagles kickoff their game Sunday … but, he was able to enjoy a relaxing pregame moment on the field before the match — chatting up his former costar Terry Bradshaw.

The actor stopped by the set of “Fox NFL Sunday” — the broadcast network’s popular pregame show — and, dapped up the former Pittsburgh Steelers star while live on-air.

BC says he wanted to come by and say hi to Terry because they worked on the movie “Failure to Launch” — starring Matthew McConaughey and Sarah Jessica Parker — back in 2006, and they’ve remained good friends since.

The other guys on-set — never ones to miss an opportunity to rib their colleague — ask Bradley if he’s still traumatized from Bradshaw’s nude scene in the flick. Check out the full clip to hear his response.

BTW … after BC leaves the set, the camera cuts to Tom Brady on the sideline — who dated Bradley’s baby mama last year. Could make for an awkward pregame hello.

As you know … Bradley’s a big fan of the Eagles — and, last week, his better half Gigi Hadid had to calm him down during a stressful game, which ended in a 28-22 victory.
