After six weeks at a treatment facility for a health-related issue, Mary-Kate Olsen, the brunette half of the Olsen twins, is "doing well" and her fans can "expect her to return home soon," her publicist, Michael Pagnotta, said Tuesday.

The 18-year-old actress has been reported to be battling an eating disorder.

People magazine reported this week that Mary-Kate will be released this weekend, return home to her family and begin preparing for college in the fall.

Mary-Kate, and her blond twin sister, Ashley, turned 18 in June. They plan to attend New York University in the fall.

They've been acting together since they were 9 months old, most notably on the sitcom Full House and in a series of direct-to-video movies. They've also attached their names to a line of products ranging from clothing to beauty items to home decorating merchandise.

Their big-screen debut, New York Minute, did poorly at the box office after its May release.
