Mary-Kate Olsen helped host
Ed Westwick honor Burberry Creative Director
Christopher Bailey at the Barneys store in New York City on Monday night (March 17).
I met the 22-year-old
Olsen twin at the event, where her artist/DJ boyfriend
Nate Lowman provided the music (pictured here in the red plaid).
MK told me all about the night before at the
Metropolitan Opera Gala. "It was my first time,"
MK shared.
