Sparks flew between the pair after filming began for the upcoming independent drama, but, nine months into the relationship, Hairspray star Snow, 23, has called it quits with the actor/producer.
Reports suggest tension on the set caused the pair to part ways.
A source tells American magazine Star, "(The relationship) got too serious too fast. They were seeing each other every day from the start."
A spokesperson for Snow had yet to respond to requests for a comment as WENN went to press.
