Dunzo: Daisy Lowe and Mark Ronson

By

Mark Ronson and his model girlfriend, Daisy Lowe, have broken up. We don't know why, but it sounds like they might have ended things on this side of the pond. They were seen together last week celebrating Ronson's 33rd birthday at a home in Buckinghamshire in the English countryside but "parted" in New York during Fashion Week. Fashion Week is supposed to bring people together, not tear them apart! [People]
