Is it a friend? A costar? A boyfriend? Until Scarlett Johansson sets the record straight, the rumor mill seems content to focus its speculation on the latter.
The 27-year-old actress got tongues wagging this week, when she stepped out in NYC with a new mystery man on her arm, holding hands with the hunky older dude all over the Big Apple (with an even bigger smile on her face).
So, who is that all but masked man?
The mystery's still out on the becapped bro, though RadarOnline claims he's an advertising executive named Nate.
But if their Saturday morning après workout stroll is in fact more than platonic, it won't be the first man ScarJo has coupled up with since her divorce from Ryan Reynolds (himself no stranger to the odd rebound).
That distinction went to Sean Penn, with an honorable if ultimately disproven mention accorded to Joseph Gordon-Levitt, a longtime pal of the actress, who was rumored, however briefly, to be slightly more than that last fall.
In any case, we haven't seen Scarlett look this happy in front of paparazzi for a long time. So whatever she's up to, it's working!
