The real reason the 'Spiderman 2' couple split is blamed on cheating! But who did?
According to HollywoodLife, 'The Amazing Spider-Man confessed having a one-night stand while away from his live-in girlfriend.
OK magazine reports that, ''Andrew allegedly told Emma that he met a girl in a bar and that it was a one-night stand, and that he would never dream of doing anything like that ever again.''
The magazine's source claims Emma was devastated by Andrew's confession and that's when she decided to halt their relationship.
Emma and Andrew now live separately after their reps announced their shocking split last March.
