Actress-turned-fashion mogul Mary-Kate Olsen has gone public with the new man in her life - sneaker designer Seth Campbell.
The 24 year old has been spotted with Campbell on a number of occasions in New York, and Olsen introduced her new boyfriend to her friends and family when they joined her actress sister Elizabeth for her birthday bash last week.
A source tells UsMagazine.com, "Their relationship is fairly new. They've been able to have a few dates on the down low...
"His company is in the press but he's not, so it works out that way. They're both like each other and are just seeing where things go. Having fun."
Olsen has been single since splitting from artist Nate Lowman a year ago.
Olsen stars in the upcoming film "Beastly" in which a curse transforms a handsome and arrogant young man into everything he detests. It's a contemporary retelling of "Beauty and the Beast."
