Olsen is now living in New York City's Upper East Side after spending her summer in the Hamptons, recovering from her breakup, ET's source noted. "She's doing great and seems happier than she's been in a long time," the source said.

Olsen doesn't often give interviews, but she and her twin sister Ashley spoke to British Voguelast year about their fashion line The Row and why they don't have an interest in acting again these days.

“We’ve been there, we’ve done that, we started out that way,” Mary-Kate Olsen said with a sigh. “But this is the way we chose to move forward in our lives: to not be in the spotlight, to really have something that speaks for itself.”

She added later that “there is a lot of pressure we put on ourselves. I feel like we’re really lucky that we have a great partnership and that we can rely on each other for support, because I can imagine it can be so lonely.”

The twins described the pressure as "self-inflicted," with Olsen adding, “If you want things to be perfect or beautiful, it’s a lot of hard work… Nothing comes easy. That’s just the way we were raised; that’s what we believe is necessary to do something different.”
