Leonardo DiCaprio attended the ceremony as a Best Actor nominee for his performance in Paul Thomas Anderson’s film One Battle After Another.
Although he ultimately lost the award to Michael B. Jordan for Sinners, his film won Best Picture and went on to become the evening’s biggest winner, taking home six Oscars in total, including Best Director and Best Adapted Screenplay.

She did not walk the red carpet with him but was seated with him inside the venue.
As the actor’s fitted custom Dior tuxedo look circulated online, the conversation quickly shifted to his noticeably slimmer appearance, which many fans speculated was due to the popular diabetes medication O**mpic, known for its weight-loss effects.
One user wrote, “He knew to get on the O**mpic to secure… second Oscar.”

“Is Leo on O**mpic? He slimmed down very quickly,” a second user questioned, while a third added, “Leo clearly used O**mpic after getting the very young girlfriend.”
Others echoed sentiments like, “Leonardo DiCaprio looking kind of hot was not on my bingo card,” and “To be fair, he looks better than he has in a while.”
“D*mn. O**mpic is working, dress shirt doesn’t even fit anymore.”
Leonardo also debuted a bold chevron mustache, with fans joking that he had “stolen” the look from actor Pedro Pascal, who appeared at the same ceremony clean-shaven for the first time in years.

Amid this wave of speculation about what could have contributed to the Titanic star’s “healthier” appearance, experts instead pointed to certain lifestyle changes.
Dr. Anil Shah, a facial plastic surgeon, exclusively told the Daily Mail that the actor’s slimmer physique could be attributed to cutting out alcohol, which is known to reduce facial inflammation and bloating.
Dr. Shah explained, “Al**hol is a toxin and studies show that it will age you faster, including your brain, your skin, your face – everything.”

Meanwhile, according to Dr. Anthony Brissett, a facial plastic surgeon and president of the American Academy of Facial Plastic and Reconstructive Surgery, there has been a “real shift” in attitudes toward cosmetic procedures among men.
As Leonardo’s appearance in recent years has sparked ongoing plastic surgery speculation, Dr. Brissett did not directly address the rumors but told the publication, “Today's male patient sees both surgical and non-surgical treatments as self-investment, helping them look rested, healthy, and confident without obvious signs of surgery thanks to the advancements in technology and techniques.”
“Advancements in technology have made facial plastic surgery more precise, less invasive, and far more natural-looking. When men realize they can enhance their appearance without long downtime or obvious signs of treatment, they feel much more comfortable taking that first step.”

Last year, while attending the 2025 Cannes Film Festival, DiCaprio faced similar speculation.
At the time, facial plastic surgeon Konstantin Vasyukevich noted that DiCaprio’s facial features showed noticeable volume loss in areas such as the cheeks and midface, which can occur with significant weight reduction, potentially linked to medications like O**mpic.
The surgeon told RadarOnline.com, “This type of change is often associated with overall weight reduction, which may occur naturally or as a result of medications like O**mpic that promote significant weight loss.”

While the 51-year-old has not addressed these speculations, some fans have defended him against the weight-loss medication and plastic surgery accusations, arguing that his transformation likely stems from lifestyle changes, possibly in preparation for his new role in Martin Scorsese’s What Happens at Night.
Moreover, his drinking and partying habits are well known to fans and industry insiders.
Rolling Stone previously reported that Leonardo “likes to order two drinks at a time, one with caffeine, one with al**hol. Some kind of balance thing.”
However, the star has consistently denied ever indulging in illegal substances, telling the Los Angeles Times in a 2014 interview, “Never done it.”
“That’s because I saw this stuff literally every day when I was 3 or 4 years old. So Hollywood was a walk in the park for me.... I’d go to parties, and it was there and, yeah, there’s that temptation.”
The Inception star concluded by reflecting on how it affects young actors in the industry, saying, "It’s incredibly vulnerable to be an actor and also get criticism at a young age when you’re formulating who you are. We’ve seen a lot of people fall victim to that, and it’s very unfortunate.”
“Leo successfully did whatever it is that Zac Efron was trying to do with his jaw,” wrote one social media user
