James Franco appeared on Conan last night to promote surprise hit Planet of the Apes, and he revealed that he once made a sex tape!

How refreshing -- a celeb who's not ashamed! Funnily enough, Franco is so weird when it comes to everything else, that the way he talks about making the tape seems normal! Said Franco:

    "My girlfriend and I decided to film ourselves. Watched it back and said, 'Yeah, well -- let's never watch that again.'"

Refreshingly humble! We bet you looked good, James!
