Olsen Interns: Mary-Kate And Ashley Pay Their Dues

Multimillionaire sisters run errands for designer, photographer.

While they may be media moguls with a combined net worth of around $300 million, Mary-Kate and Ashley Olsen are not above getting coffee for the boss. As part of their requirements at New York University's Gallatin School of Individualized Study, the twins have scored some sweet internships as first-year students.

Mary-Kate is working for A-list celebrity photographer Annie Leibovitz. Leibovitz, regularly published in the glossy pages of Vanity Fair, photographed the sisters as part of an advertising campaign for A&E's "Biography" last year. Mary-Kate's responsibilities are not likely to include handling film or anything potentially disastrous, but rather running errands, filing and other basic chores.

"They're having a chance to explore things that interest them that they never had a chance to do. It's an opportunity for both of them to learn from the best," said their rep.

A source close to the twins confirmed rumors that Ashley is interning with designer Zac Posen. She's probably not sketching out dress designs or cutting patterns, but, like Mary-Kate, is likely doing more standard gofer work — though she is no stranger to the design world. Seated in the front row at some of the top fashion shows, Ashley and her sister already tried their hands at designing, having launched their own line — aptly named mary-kateandashley — in 2001.

While they are earning credits, the NYU program promotes internships. The Gallatin School for Individualized Study's Web site explains the school's focus on practical experience: "The work may relate to the student's intellectual or creative goals or may be based on learning experiences related to the student's professional and career aspirations." Just in time, too. The twins have recently taken over management of Dualstar Entertainment, the company behind their $1 billion business empire. They have been co-presidents of the company since turning 18 last year.
