Ben Affleck revealed a big secret this weekend: His dolphin tattoo!
While it's been reported in the past that he covered up a high school girlfriend's name with some ink of the sea mammal, we've never seen it before ... until now.
Jen Garner's man -- who's sporting a Justin Bieber 'do for a new movie -- showed off the ink while out with his family over the weekend.
Besides the dolphin, Affleck also has a barb wire tatt on his bicep, a cross on his left arm and roman numerals on his shoulder.
