Teen mogul Mary-Kate Olsen has decided return to the prestigious New York University, after dropping plans to study outside of the Big Apple.

The 19-year-old and her twin sister ashley moved from California to New York at the end of 2004 to take up their studies, but speculation Mary-Kate was eager to study elsewhere was rife.

But Mary-Kate has now opted to stay in New York, according to her representative MICHAEL PAGNOTTA, who says, "Mary-Kate is back at NYU taking classes. She changed her mind. She is not pursuing her independent study outside of New York."
