Robert Pattinson All Smiles on Set After Security Guard Scuffle

Robert Pattinson appears to be in a good mood while filming scenes for his movie Maps to the Stars on Saturday afternoon (August 17) at Union Station in Los Angeles.

The night before, the 27-year-old attended a concert at The Troubadour and was mobbed by photographers and fans while exiting the venue.

While being ushered to his car by a team of security guards, Rob appeared to mistake one of the guards for a paparazzo and reportedly shoved the man to try and get him out of his way. Check out video of the incident on TMZ.
