Charlie Hunnam -- I'm Still the Best Man ... For My Friends Wedding

Charlie Hunnam appeared front and center for his friends wedding yesterday -- not phased at all over DROPPING OUT OF THE ONE OF THE MOST ANTICIPATED MOVIES EVER!!

Hunnam watched his buddy tie the knot in Santa Barbara yesterday ... just hours after Universal announced he was bailing on the "Fifty Shades of Grey" movie.

Charlie also gave a toast at the reception and was in great spirits ... according to reports.

No word on whether or not Robert Pattinson, Matt Bomer and Ian Somerhalder were invited.
