She was Hollywood’s classiest eccentric. He was pop’s most famous rebel. Somehow, they shared one of the most unlikely and heartwarming connections in entertainment.

Before Diane Keaton passed away on October 11 at age 79, she left behind an unforgettable legacy: Oscar-winning roles, scene-stealing style, timeless charm — and one surprisingly adorable friendship with none other than Justin Bieber.

Yes, you read that right.

Long before she appeared as Bieber’s on-screen grandmother in his poignant 2021 “Ghost” music video, the Annie Hall legend and the pop superstar shared a moment so charming, so unexpected, and so delightfully unscripted, it could have been pulled straight from a romantic comedy.

And it all started with a Calvin Klein ad and a lot of blushing on daytime TV.

Their First Encounter: Bieber Week, 2015

The year was 2015. Keaton, already an icon of film and fashion, was a guest on The Ellen DeGeneres Show during what the host called “Bieber Week.” The celebration was timed to a string of Justin’s appearances — fresh off his 21st birthday and his dramatic career comeback.

For Diane, the visit started innocently enough. But when Ellen brought up the subject of Justin — and specifically showed a few of his now-iconic Calvin Klein underwear ads — things got a little more animated.

“Okay! That is not possible. I had not seen that. That is gorgeous,” Keaton exclaimed, visibly stunned.
“Wow, I mean okay. Now we’re talking!”

The studio audience roared with laughter as Keaton’s signature brand of elegant awkwardness turned into full-on fangirling. DeGeneres, ever the mischief-maker, even handed her a turtleneck printed with Bieber’s face. When she jokingly asked if Diane considered herself a cougar, Keaton fired back:

“Well I’d like to, except I haven’t had the opportunity — except when I have a job!”

Cue the surprise entrance.

Justin Bieber snuck onto the stage behind Keaton, and her reaction was immediate and unforgettable — covering her face, yelling in surprise, and then giving him a warm hug and kiss on the cheek.

“It was really nice meeting you,” she said, almost breathless as he exited the stage. “Bye!”

The clip instantly went viral, a mix of humor, admiration, and sweetly unexpected chemistry between two stars from totally different worlds.

A Video Call That Became a Music Video

Six years after that memorable moment, Justin Bieber made the call that would turn their flirtatious TV banter into on-screen collaboration.

In 2021, Keaton starred in Bieber’s music video for the ballad “Ghost,” directed by Colin Tilley. The video’s storyline followed a young man helping his grandmother cope with the death of her husband — taking her on walks, dancing with her in the kitchen, and reminding her how to live again.

Keaton brought depth, soul, and a touch of whimsy to the role. The performance was subtle but emotionally powerful — so much so that it became one of Bieber’s most talked-about and critically appreciated videos to date.

And for Keaton?

“I couldn’t believe it. I still can’t believe it,” she said in a 2023 interview with Metro U.K. “It was like one of those things that happens and you go, ‘I’m what? Me?’”

She gushed about the experience, calling it “so much fun” and praising Justin for being “kind to everyone” and surrounded by a team that made her feel at home.

“I Wasn’t Even a Fan, Exactly…”

In typical Diane Keaton fashion, her honesty about the experience was refreshingly unfiltered. Despite her fangirl moment on Ellen, she later admitted that she hadn’t been a longtime Bieber fan before appearing in the music video.

“I mean, I didn’t even know him,” she told Metro. “I knew the music a little and I liked the music, but I wasn’t a fan exactly — so you know, I don’t have music pouring in my ears all the time.”

She added, with her trademark laugh, that she wasn’t sure why she had been chosen for the role — but she was glad she said yes.

“I don’t know why me, I still don’t understand,” she said. “But I loved it.”

In many ways, that simple statement sums up Keaton’s charm: a woman who never chased the spotlight, but somehow always ended up in the middle of its glow — arms open, turtleneck on, completely herself.

Two Icons, One Unexpected Connection

On paper, it was an unlikely friendship.

Keaton — the Oscar-winning actress known for playing neurotic intellectuals and lovable eccentrics in films like Something’s Gotta Give, Father of the Bride, and The First Wives Club — represented a Hollywood of a different generation.

Bieber, on the other hand, had grown up in the YouTube era, launched into superstardom as a teenager, and weathered public scandals, reinventions, and a very different kind of media scrutiny.

And yet, when they crossed paths, they found something in common: openness, humor, humility — and maybe a little mutual admiration.

A Final Tribute to a Bond That Brought Smiles

In the days following Keaton’s death, fans revisited the “Ghost” video in droves, viewing it now with fresh eyes and deeper emotion. For many, it wasn’t just a music video anymore. It was one of Diane’s final performances — and a fitting farewell to the kind of quiet grace she brought to every screen she graced.

Though she was known for her roles in some of cinema’s most iconic films, Keaton’s late-life embrace of projects like Ghost and her playful spirit with younger stars like Bieber made her feel timeless.

She never stopped exploring. She never stopped surprising us.

Remembering Diane Keaton — One Laugh, One Hug, One Music Video at a Time

There will be countless tributes to Diane Keaton in the months ahead. Film retrospectives. Award show honors. Replays of Annie Hall and The Godfather.

But perhaps one of the most unexpected — and most endearing — tributes will be a hug she gave a pop star on a talk show stage, and a quiet, moving performance in a four-minute music video about love and loss.

Because that’s who Diane Keaton was.

Not just a legend. Not just a fashion icon. But a woman who could make you laugh, make you cry — and make you believe that anything, even an unexpected friendship, was possible.

Rest in peace, Diane. And thank you — for the roles, for the words, and for reminding us that joy is ageless.
