The young actress had been tweeting about how she was alone for the holidays and wanted to call a fan to lift her mood.
It is not clear if any of the five models who have died recently knew one another.
What prompted her suicide remains unclear but in the days beforehand, she found herself in the center of a firestorm on Twitter after publicly saying that she had refused to work with a man she knew did both straight and gay scenes.
The first death was that of 35-year-old Shyla Stylez.
In December, actress August Ames, 23, hanged herself in California, where she lived with her husband.
At first, it was suspected that drugs or alcohol may have played a part in her death.
