Mark Wahlberg might've been a week early and minus a Floyd Mayweather ... but he still had the best seat in the house to watch Manny Pacquiao today ... dropping in on Pac Man's gym session.
Wahlberg brought his entourage (see what we did there) to Wild Card Boxing in Hollywood and got an up close and personal look at the Filipino slugger just days before the May 2nd mega fight.
Things had been really tight at Wild Card recently -- with Manny's trainer Freddy Roach restricting anyone who wasn't on the training staff from watching Pacquiao work ... including Dave Chappelle.
Guess Whalberg can keep a secret ... 'cause it was all smiles and handshakes today as Mark's crew got full access to watch the strategy that could finally put a blemish on Mayweather's record.
