Matt Damon admits to have seen Ben Affleck's 'wiener'

Matt Damon has admitted that he has seen actor Ben Affleck's "wiener" many times.

According to TMZ.com, Affleck's 'Gone Girl' features a scene where his thing is bare, and during an event, which Affleck was also attending, Damon, 44, was asked if he saw his "pal's junk in the flick."

However, while fans of the movie said that it was briefly visible, some say it didn't even happen.
