Robyn Lively publicly supported her sister Blake Lively on Instagram for her 37th birthday amidst ongoing criticism related to Blake's promotional approach for her new film, 'It Ends With Us.' In her heartfelt tribute, Robyn expressed her love for Blake, calling her one of the best humans she knows. Fans chimed in, defending Blake against negative media portrayals, which Robyn acknowledged with gratitude. The backlash stems from purported drama during the film's press tour and criticism of Blake's perceived 'tone-deaf' approach, contrasting with the film's serious themes of domestic abuse. Despite the negativity, Blake celebrated her birthday with friends, including Ryan Reynolds and Taylor Swift, while keeping a lower profile. The situation has sparked discussions about the dynamics on set and the challenges of promoting such a sensitive film.
