This was snapped in the summer at Pre Lachaise in Paris NOT Monte Carlo during the filming time fram of Monte Carlo. Pop Sugar is calling him her boyfriend.
-b>click for story. It may be part of the movie and not them romancing each other on their own time. If she is dating the hunky Australian (who just happens to look a lot like Garrett Hedlund) it means that the reports of Garrett and Taylor are true!
If she was having a flirt with Luke when Garrett was away filming On The Road, then Leighton has some explaining to do. Nice girls don't do that when nice guys tell them they love them.
