Fans are thrilled that Katie Holmes and Joshua Jackson are back together again - even if it's just for a movie. The pair were spotted filming the upcoming trilogy Happy Hours together in New York City on July 21. Jackson was wearing a green button-top shirt while Holmes wore a pink flannel over black pants. They were later spotted again, pushing a baby stroller while filming for the same film. The project is the first for the pair since their hit teen series Dawson's Creek ended in 2003.
