Actress Mary-Kate Olsen announced she's thinking about "a leave of absence from her studies at New York University", American People magazine reported Friday.

Olsen's spokesperson stated that the actress wants to "focus on her increasing responsibilities as co-president of Dualstar Entertainment Group and to pursue personal interests".

'She`s not reentering any kind of treatment facility or anything like that,' the rep said. Mary-Kate was checked during the summer into a Utah center to treat her eating disorder.

Her sister Ashley will reportedly stay at NYU.

The Olsens started their acting careers on the television series Full House in 1987. The show was widely popular during the late 80s and early 90s, and both sisters played one character, Michelle Tanner, taking turns during the tapings to do so, in order to comply with child labor laws regarding child actors.

Because the producers did not want viewers to know that Michelle was played by twins, the sisters were originally credited as "Mary Kate Ashley Olsen", but later credited as separate people.

Shortly after the end of Full House, they have returned to the entertainment industry, riding the momentum of their role on Full House by heavily merchandising their image.

Taking the world of pre-teens and children by storm, their names have become a very profitable industry, with their likeness seen in movies, posters, magazines, clothes and even video games, like Mary Kate and Ashley's Magical Mystery Mall.

As of 2005, Mary-Kate and Ashley are popular figures in today's pre-teen market, following along the lines of such Hollywood child stars as Shirley Temple, Ron Howard and Macaulay Culkin, among others.

They starred in The Adventures of Mary-Kate and Ashley and the ABC show Two of a Kind (now rerun on ABC Family), as well as ABC Family's So Little Time.
