Mary-Kate Olsen is Dating Artist Nate Lowman

Mary-Kate has been linked to a string of men, but has been officially single since 2005 when she split from Stavros Niarchos III.

The 21-year-old actress has been spotted with the 29-year-old artist at several New York nightspots including the Beatrice Inn. A source said: "They have a love connection. They're dating. They are such a cute couple."

Mary-Kate - who has made a fortune turning her name into a global brand with identical twin Ashley - became a big art fan after appearing as an extra in last year's Andy Warhol movie 'Factory Girl', and began collecting the iconic artist's work. She is currently at Utah's Sundance Film Festival promoting her new movie 'The Wackness' in which she kisses 64-year-old 'Ghandi' star Sir Ben
Kingsley.

Colin Farrell - who is also at the festival to attend the premiere of his new movie 'In Bruges' - was spotted trying to woo the Olsen twin but his advances were spurned. A source said: "Colin was clearly taken with Mary-Kate and snuggled up to her on the couch at the bar. I'm not sure if the feelings were mutual, though!"

Mary-Kate has been linked to a string of men, but has been officially single since 2005 when she split from Greek shipping heir Stavros Niarchos III, who has since dated Paris Hilton on-and-off.
After the split, Mary-Kate was left heartbroken and took a leave of absence from her studies at New York University. She said at the time: "I miss him and I love him. It's a hurtful and a painful subject."
