Is Scarlett Johansson Dating Kieran Culkin?

Was a romance blooming, or was it just two old friends reconnecting when Scarlett Johansson and Kieran Culkin spent time in the City of Love last week?

The actress, seen on a romantic stroll through Paris with Culkin on Sept. 13, was reportedly in town to shoot a video. Johansson, 26, and the Scott Pilgrim vs. the World actor, 28, appeared cozy and happy as they made their way along the Champs-élysées after midnight.
