Joshua Jackson is clocking in for his shift as the No. 1 Katie Holmes fan 🫡 After the former #DawsonsCreek stars attended the world premiere of Holmes' latest directorial effort, 'Happy Hours,' Jackson posted a gushing tribute to his longtime friend, and now director, on social media. "This is a Katie appreciation post... She is such an incredible friend that she made the space for us to be able to play together again after all these years. I was amazed when we were kids and she was the bravest most raw of us telling the truth in every moment. And I am amazed now to watch her as a leader, with the same commitment to kindness, strength through compassion, to truth and the essential hopefulness of existence. I hope you all enjoy this movie as much as I did. And you can be amazed by her too." 📷 Getty Images
