From her early breakout days in teen cinema to her evolution into a box-office leading lady and executive producer, Lively has spent over two decades commanding the screen with effortless charisma.

To honor her birthday, here are 7 of her most memorable and career-defining performances.

1. Serena van der Woodsen – Gossip Girl (2007–2012)

As the magnetic, effortlessly chic “It Girl” of Manhattan’s Upper East Side, Lively delivered one of the defining television turns of the 2000s. Her portrayal of Serena van der Woodsen launched her to global stardom overnight and cemented her status as an enduring pop-culture style icon.

2. Emily Nelson – A Simple Favor (2018)

In Paul Feig’s sharply stylish comedy-thriller, Lively delivered a tour-de-force performance as the enigmatic, martini-swilling, suit-wearing Emily Nelson. Opposite Anna Kendrick, Lively brought dark, chaotic wit and razor-sharp charm to the screen in one of the most critically praised roles of her career.

3. Kris Coughlin – The Town (2010)

Stepping well outside her Gossip Girl image, Lively delivered a gritty, scene-stealing dramatic turn as the troubled Charlestown mother Kris Coughlin in Ben Affleck’s crime thriller. Her grounded, raw performance earned high marks from critics and proved her range as a dramatic heavyweight.

4. Adaline Bowman – The Age of Adaline (2015)

Anchoring Lee Toland Krieger’s romantic fantasy, Lively brought timeless sophistication and quiet emotional weight to Adaline, a woman who miraculously stops aging at 29. Her performance carried the nearly century-spanning narrative with grace, romance, and understated heartbreak.

5. Nancy Adams – The Shallows (2016)

In this tense survival thriller, Lively virtually carried the entire feature on her shoulders as a medical student and surfer stranded on a rock facing off against a Great White Shark. Relying on physical grit and sheer screen presence, she turned the tight thriller into a massive critical and commercial hit.

6. Bridget Vreeland – The Sisterhood of the Traveling Pants (2005)

In her breakout film role, an 18-year-old Lively played Bridget Vreeland, an athletic star grappling with personal grief and self-discovery during a summer away in Baja. Lively captured both the outward exuberance and quiet sorrow of youth, instantly marking her as a star to watch.
