While girls at her age are busy with their school tasks, Mary-Kate Olsen has something else to do. This of course more important than her college classes that she has to reluctantly take a leave of absence from New York University. The teen actress apparently does not drop out, "she has simply taken an approved leave of absence to devote more of her time and energy to her business," her representative Michael Pagnotta said.

Mary-Kate is said to focus on the entertainment company she runs with her twin sister, Ashley Olsen, who will remain at New York University's Gallatin School, where they are sophomores studying a liberal arts curriculum. Pagnotta explained further "She and her sister run a global business and it demands quite a bit of their time." Mary-Kate would in November return to New York to accept a fashion award.
