Would you ever want to see your children doing the dirty in the red room of pain? Would you ever want to see your children getting sexually spanked or making love all night long?


WE WOULDN'T and neither does '50 Shades' star Dakota Johnson's parents..sort of. 


Dakota's mom and dad, Don Johnson and Melanie Griffith, have been BANNED from seeing the movie... by Dakota herself!


In her defense, the movie is expected to be EXTREMELY KINKY. Her parents were not even allowed to visit her on the set.


Griffith has visited her daughter on set before, while she was filming more "normal" things.
