In the often fickle world of Hollywood friendships, there are few bonds as genuine and enduring as the one between Jennifer Aniston and Adam Sandler. Having worked together on several films over the years—from the tropical rom-com Just Go With It to the wildly successful Murder Mystery series—the duo has formed a connection that extends far beyond the film set. And now, thanks to a recent interview, fans are getting a charming peek behind the curtain into their off-camera dynamic, starting with the hilarious nicknames they’ve given each other: “Anaburger” and “Sandalman.”

During a press tour for Murder Mystery 2, the co-stars appeared on Entertainment Tonight where they revealed their playful pet names. Aniston affectionately refers to Sandler as “Sandalman”—a nod to his famously relaxed fashion choices, particularly his penchant for wearing sandals almost everywhere, especially in his laid-back Malibu lifestyle. “Sandalman” is part pun on his last name and part tribute to his chilled-out, beach-ready persona.

Sandler’s nickname for Aniston is even more unexpected—and definitely fast food-inspired. He calls her “Anaburger,” a mashup of “Ana” from Aniston and “burger,” though Aniston has been vocal about her health-conscious lifestyle and doesn’t exactly indulge in burgers often. Still, the nickname has stuck, much to fans’ delight. While neither star provided a detailed explanation for the origins of the names, their laughter and comfort with one another said it all: this is a friendship built on years of mutual respect, shared humor, and the kind of bond that only deep familiarity can forge.

Their exchange during the ET interview was peppered with jokes and genuine affection. Aniston, 54, teasingly asked Sandler, 56, what the “best part” was about being her on-screen partner. Without missing a beat, Sandler responded with heartfelt—and hilarious—praise: “You certainly have a way about making life fun on the set. You’re caring. You care about how I’m doing, if I’m enjoying my life, if I’m healthy.” He even joked that she takes the time to make sure his beard smells nice and, after kissing scenes, politely leaves the room to scream, “What the hell was that?”

The duo’s easy chemistry isn’t limited to interviews. It translates directly to the screen, where their natural banter and comedic timing make their roles feel effortlessly believable. In Murder Mystery 2, which premiered on Netflix on March 31, their characters Nick and Audrey find themselves entangled in yet another outrageous whodunit. Set four years after the events of the original, the sequel shows the couple as struggling private detectives trying to revive their agency. They’re invited to a lavish wedding on a private island, hoping for a relaxing getaway—but end up in the middle of chaos once again.

Speaking on The Tonight Show, Aniston hinted at the comedic madness fans can expect. “When you meet back up with us, we’re not doing that great,” she told host Jimmy Fallon. “So we get invited to a wonderful wedding of someone wonderful, we say: ‘We need a break, we need a vacation.’ And that’s where our mistakes happen.”

But beyond the scripted laughs and dramatic twists, it’s the off-screen dynamic between Sandler and Aniston that fans adore. Their friendship—rooted in trust, loyalty, and a shared sense of humor—has spanned decades. Long before Murder Mystery, the pair were already close friends, often speaking fondly of each other in interviews. Sandler has said that Aniston is one of the few people in Hollywood he truly trusts, while Aniston has described him as “family.”

Their quirky nicknames are more than just inside jokes. They’re little windows into a relationship that defies the usual Hollywood churn of temporary co-star alliances. In a world where many celebrity connections fade after the credits roll, Aniston and Sandler have nurtured something rare: a bond that’s lasted through changes in career, lifestyle, and life itself.

“Anaburger” and “Sandalman” might sound silly to the outside world, but within their private universe, those names are signs of something special. They speak to a level of comfort and familiarity few co-stars ever reach. Fans love them not just because they’re funny or talented—but because their friendship feels real, grounded, and refreshingly goofy.

As Murder Mystery 2 brings more laughs to screens worldwide, the real magic continues behind the scenes—between two friends who never take themselves too seriously and who, through shared jokes and offbeat nicknames, remind us all what lasting friendship can look like in the limelight.
