was hit by a taxi after being mobbed by a group of female fans.
The 'Twilight' actor - who is in New York filming new movie 'Remember Me' - attempted to run across the road to escape the horde of young girls and was clipped by a moving cab.
Fortunately, the driver slammed on his breaks upon impact and the 23-year-old heartthrob walked away from the incident unharmed.
Sources on the set of the movie say they aren't surprised by the incident as Robert is swarmed by girls wherever he goes.
One told People magazine: "It's non-stop busy all day with people trying to get a glimpse of him, and the crowd goes nuts when they do see him."
Although Robert - who plays vampire Edward Cullen in the 'Twilight' films - has had to hire extra security to protect him, the star is grateful to have so many fans.
The source added: "I think he appreciates it. He's not one to make a big deal about it. He's a chilled guy. I think he finds it a little weird that people are standing outside all day to get a glimpse of him, but he's definitely grateful."
