Columbia University honored Rubenstein in 2004 by naming her one of the top 250 alumni through the ages.
She is a member of the Candie’s Foundation Board of Directors, which helps educate young people about the consequences of teen pregnancy.
This made Rubenstein, who was 26 years old at the time, the youngest editor-in-chief in Hearst Magazine's 100-year history.
