The Transformation Of Leonardo DiCaprio From 3 To 46 Years Old

Leonardo DiCaprio is one of the most renowned actors in Hollywood — and with good reason. The award-winning actor, who was born in November 1974, has enjoyed a long and highly successful career in tinseltown. According to his website, DiCaprio started acting when he was just 14, making his career steadfastly successful for more than 30 years.

Like many actors, of course, DiCaprio had a small start and slowly worked to gain notoriety in Hollywood. In 1991, DiCaprio landed his first semi-regular role in the TV comedy Growing Pains, while also making his film debut in the horror movie Critters 3 that same year. The '90s would prove to be pivotal for DiCaprio's career. He started the decade as a clunky teen, taking small roles in low-budget productions. He ended the decade as one of Hollywood's hottest young actors and American heartthrob, and he certainly didn't stop there.

Over the course of his decades-long career, DiCaprio (pictured above at 3-and-a-half years old) has experienced a huge transformation in both his professional and personal life — let's take a look back at some of his most crucial moments. 

'Titanic' catapulted Leonardo DiCaprio into fame

Though Leonardo DiCaprio got his start in smaller roles, he quickly landed bigger film roles that put him on the map. One of his biggest breakthroughs came in 1993, when DiCaprio (seen here at the 1998 Golden Globes) starred alongside Robert De Niro in This Boy's Life. That same year, he starred in What's Eating Gilbert Grape, along with Johnny Depp. Many consider this his official transition from up-and-coming actor to Hollywood star. DiCaprio's work in the film earned him an Oscar nomination for supporting actor — and, though he didn't win, it represented the first of many award-worthy performances to come. 

In 1996, DiCaprio landed the role of Romeo in Romeo + Juliet, alongside fellow up-and-comer Claire Danes. And, if playing one of the most iconic literary characters of all time wasn't enough to establish DiCaprio as a heartthrob, his next big role certainly would. In 1997, DiCaprio starred alongside Kate Winslet in Titanic, which proved to be one of the most pivotal points in the young actor's career. He'd already garnered plenty of fame before the film, but after taking on the role of Jack Dawson, DiCaprio's life was catapulted into the spotlight.

Fans and critics couldn't get enough of the movie, and though DiCaprio wasn't nominated for an Oscar, the film itself won a slew of awards. Titanic helped solidify both DiCaprio and Winslet as stars, but it also solidified a friendship between the two that would last for decades.

The actor saw success in his personal life, too

As the new millennium began, Leonardo DiCaprio's career continued to flourish. While the actor's film performances garnered attention within the media, they weren't the only thing to do so. Though DiCaprio has remained quiet about his dating life over the years, fans have been naturally curious. And, as it turns out, the Catch Me If You Can actor found his way into the Hollywood dating pool quite comfortably.

With a penchant for models, DiCaprio has enjoyed his fair share of relationships over the years — from a rumored romance with Naomi Campbell in the '90s to his current relationship with Camila Morrone, the actor has had some high-profile relationships. One of his most memorable relationships was with supermodel Gisele Bündchen, whom DiCaprio dated from 1999 to 2005, according to Elle. DiCaprio was relishing in an established film career by this point, and Bündchen was one of the hottest models in the industry. Together, they were a mesmerizing couple, and after a six-year romance, it became one of DiCaprio's longest relationships to date.

The couple maintained a pretty low-key relationship, with their appearance at the 2005 Oscars (pictured above) being one of the few glimpses the public got of the duo together. Bündchen would later go on to talk about their breakup in her memoir, insinuating that lifestyle differences ultimately forced the pair to go their separate ways.

Leonardo DiCaprio is a passionate environmental activist

Leonardo DiCaprio is best known for his film career and high-profile relationships, though the actor has another passion as well: the environment. Throughout his career, DiCaprio has consistently used his platform to talk about climate change and preserving the world's natural landscapes. In 1998, the actor established the Leonardo DiCaprio Foundation, which is dedicated to restoring "balance to threatened ecosystems" and "ensuring the long-term health and well-being of all Earth's inhabitants." In 2009, the actor released his documentaryThe 11th Hour, which offers a grim, but real look into what will happen to the world if climate change isn't taken more seriously.

In 2014, the United Nations recognized DiCaprio as a Messenger of Peace for his work against climate change. The actor — pictured here receiving his United Nations pin — has since returned to the Climate Summit, showing his support for the cause and giving speeches about the importance of environmental awareness. DiCaprio also uses his Instagram account to promote his activism and continue to raise awareness for ongoing environmental issues, like air pollution.

The actor's career isn't slowing down anytime soon

Now that Leonardo DiCaprio has enjoyed a 30+ year career in Hollywood, many fans wonder when the actor will slow down. Based on his continuous success and future projects, however, DiCaprio — pictured here at the 2020 Oscars — isn't stopping anytime soon. Fresh off the success of his starring role in Quentin Tarantino's Once Upon a Time in Hollywood, DiCaprio has more high-profile projects in the works. Hollywood Reporter first announced that DiCaprio would star as former president Teddy Roosevelt in the biopic, aptly titled Roosevelt. The actor is also making a rare TV run in an adaptation of The Devil in the White City, per Variety

Over the past several decades, DiCaprio has established himself as one the best actors to ever grace the big screen. From his early days on Growing Pains to his Oscar-winning performance in The Revenant, DiCaprio has come a long way as an actor. Along with his high-profile relationships and environmental activism, DiCaprio has transformed in front of our eyes over the years, while always maintaining a captivating, engrossing, and oftentimes mysterious aura about him.
