Mary-Kate and Ashley Olsen
Mary-Kate Olsen has left her studies at New York University and has temporarily gone back home to Southern California, her publicist tells PEOPLE, stressing the fact, "She is not dropping out of NYU."
Says Olsen spokesman Michael Pagnotta: "She's not leaving New York City or moving back to L.A. She is in L.A. on personal business. She is not going back into treatment (for an eating disorder that had been confronted earlier this summer). She has a team of people of both coasts whom she can access in L.A. or New York."
Pagnotta also said of the 18-year-old: "Her health is good. But there's no question an eating disorder like this has its ups and downs. She has ongoing after care."
Pagnotta calls the reports of Olsen's re-entering treatment "totally false. It's not a relapse. She is doing much better. It's damaging when people puts these rumors out there."
He adds, "She will be back in New York in a few days."
Mary-Kate and her twin sister Ashley, who apparently is continuing her studies at NYU, share a $7 million apartment near the campus. Local newspapers have been tracking their extracurricular social activities.
In June, Mary-Kate entered a clinic for treatment of an eating disorder, PEOPLE reported at the time. She remained there for six weeks.
Upon completion of the facility's program, Mary-Kate was "feeling very well," Pagnotta said at the time, adding that she would continue treatment privately while preparing to begin her studies at NYU with Ashley.
