She was three when her family moved to Queens, New York and then later to Malverne, on Long Island. As an undergraduate student at Barnard College, Rubenstein became a public relations intern at Lang Communications. Rubenstein had to take night classes to take part in her second magazine internship, which led to a position in the editorial department of American Health magazine.

In 1993, Rubenstein became a fashion assistant at Cosmopolitan and five years later was made the senior fashion editor. This led to Hearst Magazines president Cathleen Black asking Rubenstein to come up with a concept for a new magazine. Forty-eight hours later Rubenstein presented the idea of CosmoGIRL! And was offered the position of editor-in-chief. This made her the youngest editor-in-chief in Hearst Magazine’s 100-year history. Rubenstein went on to make CosmoGIRL! a success with a circulation of 1.25 million readers.

On 7 November 2006, she announced that she would be leaving the magazine to launch her own teen-centered Web business, write a book and start a consulting firm specializing in the youth market. In December 2006, Rubenstein started Big Momma Productions, Inc. after a thirteen-year career with Hearst Magazines.
