Joshua Jackson and Diane Kruger went shopping around Vancouver yesterday. The couple strolled the streets arm in arm and stopped inside a local boutique to browse before engaging in a sweet show of PDA. Josh and Diane are back together in Canada, where Josh is filming the final season of Fringe, after Diane's travels took her around the country. She popped up in LA at the end of November for the Hollywood Foreign Press Association's Golden Globes celebration and stepped out in NYC last weekend for a gala honoring Quentin Tarantino. Diane returned north just in time to mark the 100th episode of Fringe with Josh last Monday. It hasn't been all about work for the duo, though, who recently escaped to Mexico for vacation.
