Buff Bourne Pursued by Paparazzi

A very buffed-out Matt Damon was caught by TMZ cameras as he made his quick way through Manhattan -- who's chasing him?

The hunky action star couldn't have been nicer to our camera -- except by taking off his shirt!

"The Bourne Ultimatum" opens this Friday -- until then, watch this!
