Melanie Griffith
At age 14, Griffith began dating 22-year old actor Don Johnson.  He co-starred with her mother in The Harrad Experiment. Griffith was an extra. They had a six-month marriage in 1976. Tatum O'Neal said in her 2004 autobiography that around that time, she (then 12) and Griffith (then 18) were in an opium-fueled orgy in a Paris hotel room.
