Macaulay Culkin became emotional as he honored his late 'Home Alone' costar Catherine O'Hara during the Emmys' In Memoriam tribute. Calling her 'warm' and 'funny,' Culkin said O'Hara 'wasn't just a wife and mother' but was his mom, adding, 'By extension, she's all of our mama.' 'Schitt's Creek' stars Dan Levy and Annie Murphy also remembered O'Hara, praising her creativity, generosity and ability to bring joy to everyone around her. Culkin ended his tribute with a heartfelt reminder to viewers: 'Call your mother tonight. For real.' 📸 20th Century Fox/Kobal/Shutterstock, Getty #macaulayculkin #catherineohara #celebrity #emmys #news
