Blake Lively has been facing substantial backlash over her involvement in the film 'It Ends With Us,' primarily related to her alleged behavior towards co-star and director Justin Baldoni and her perceived trivialization of the film's serious themes. The friction between Lively and Baldoni became evident when the cast unfollowed Baldoni on social media, and reports suggested creative differences during production. Amidst this controversy, Lively celebrated her 37th birthday at Taylor Swift's lavish Rhode Island mansion, where she was joined by her husband Ryan Reynolds and other A-list friends. Her sister, Robyn Lively, publicly defended her on social media, highlighting the support Lively has from her family and fans despite the online negativity. The backlash has reportedly led Lively to reassess her career prospects, causing her to retreat from the spotlight temporarily.
