TWEEN queen Mary-Kate Olsen has taken time out from uni to focus on her entertainment empire, her spokesman has said.

Mary-Kate had already returned to Los Angeles but would visit New York in November to accept a fashion award, spokesman Michael Pagnotta said. "She’s not dropping out. She’s taking an approved leave of absence to focus on her increasing responsibilities and live her life," Mr Pagnotta said.


Mary-Kate’s twin Ashley will remain at New York University’s Gallatin School, where the 19-year-old entrepreneurial stars were sophomores studying liberal arts, Mr Pagnotta said.

"She and her sister run a global business and it demands quite a bit of their time," he said.
The mini-moguls are co-presidents of Dualstar Entertainment Group, a multimillion-dollar brand aimed at the tween market, with home videos, CDs, books, apparel, fragrances and dolls.

Fortune magazine last year estimated they were worth $US137 million ($180 million) each.
Mary-Kate, who was treated for an eating disorder in 2004, was not taking taking time out for health reasons, Mr Pagnotta said.
