Blake Lively, the acclaimed star of “Gossip Girl” and “A Simple Favor,” has found herself at odds with several celebrities over the years, leading to a mix of tension and drama in Hollywood. The complexities of her relationships, particularly with former co-stars and partners, have often made headlines, revealing a web of jealousy, competition, and unresolved feelings.

One notable rivalry emerged with Scarlett Johansson, who was married to Ryan Reynolds when he was filming “Green Lantern” with Lively in 2010. Both actresses have been linked to Reynolds, and speculation about an affair during the filming has lingered. Johansson hinted at the challenges of dating fellow actors, suggesting that competition can strain relationships, a sentiment fueled further by her public split from Reynolds.

Tensions also surfaced on the set of “A Simple Favor,” where reports indicated an uncomfortable dynamic between Lively and her co-star Anna Kendrick. The friction allegedly stemmed from competitive spirits, particularly regarding promotional materials, and personal jabs that escalated to a point where the two had to be reminded to maintain professionalism during press tours.

Even Lively’s past relationships with actors like Leonardo DiCaprio and Penn Badgley have been fraught with drama. DiCaprio’s desire for a more serious commitment reportedly clashed with Lively’s readiness to settle down, leading to a painful breakup that impacted his performance in “The Great Gatsby.” Badgley, who dated Lively during their time on “Gossip Girl,” admitted that their romance was tumultuous, leaving him in a dark place post-breakup.

More recently, Lively’s interactions with Zendaya and Brandon Sklenar have sparked speculation about rivalry. While both actresses have downplayed any tension, social media exchanges suggest a competitive undertone. Meanwhile, Sklenar’s light jab about preferring to rehearse alone rather than with Lively added fuel to the fire.

As Lively continues to navigate her career and relationships, the intrigue surrounding her connections with other celebrities remains a topic of fascination, illustrating the complexities of fame and personal dynamics in Hollywood.
