Mary-Kate Olsen Is Not New To NYC

Mary-Kate Olsen steps out to run some errands on Friday (March 20) in New York City.

Earlier this week, a glamorous Mary-Kate Olsen met up with her boyfriend Nate Lowman at Greenhouse, an eco-friendly New York nightclub. “She was dancing all night,” a club source told People.

Mary-Kate helped host Ed Westwick honor Burberry Creative Director Christopher Bailey at the Barneys store on Monday night and also showed off a new look at The Metropolitan Opera’s 125th Anniversary Gala last week.
