The Olsen Twins can stop checking the mailbox: New York University has invited them to join the Class of '08, PEOPLE reports in its upcoming issue.

"Like every other senior, they had been sweating out their acceptance and they are absolutely thrilled," their rep, Michael Pagnotta, tells the magazine, on newsstands Friday. "They have always taken academics very seriously. This is a major achievement for them."

Mary-Kate and Ashley, both 17, will be enrolled next fall at the Gallatin School of Individualized Study, a college with approximately 900 undergraduates within NYU that allows students to tailor their own curriculum according to their needs and ambitions.

The girls may have taken a shine to Manhattan after filming there earlier this year for their upcoming movie, "New York Minute."

The teen moguls will join a long list of NYU celebrity alumni, including "Will & Grace"'s Debra Messing, model Christy Turlington and actresses Camryn Manheim and Marcia Gay Harden.
