SHOCKING VIRAL MOMENT: Daniel O’Donnell Superfan’s Hilarious Reaction to Mario Rosenstock’s Impersonation on The Late Late Show
What was meant to be a lighthearted moment on Irish television has become one of the most talked-about viral clips of the week. Daniel O’Donnell superfan Molly-Kate Sloyan has revealed that she received what she calls a “fierce slagging” from her friends after her reaction to a surprise twist during The Late Late Show’s Valentine’s Day special.
The story began when the studio audience was told that Daniel O’Donnell, Ireland’s beloved singer and entertainer, would be appearing on stage. The announcement sent waves of excitement through the crowd, but none reacted with more joy than Molly-Kate, whose face lit up with sheer delight. Rising from her seat in uncontainable excitement, she prepared herself to see her idol walk out in front of her.
Instead, the audience was greeted by Mario Rosenstock, the well-known comedian and impressionist, who appeared in character as O’Donnell. What followed was a moment of television magic: Molly-Kate’s expression shifted instantly from pure joy to visible disappointment—a reaction that captured the hearts (and laughter) of viewers everywhere. Within hours of the broadcast, the clip had gone viral online, shared across social media platforms and replayed countless times.
Speaking to the Irish Daily Mail, Molly-Kate admitted she had no idea that the cameras were on her during the broadcast. “I had no idea the cameras were on me during The Late Late Show and I’ve no filter on my face, all my friends know that, so afterwards they gave me a fierce slagging,” she said with good humor.
Her friends wasted no time in reminding her of the moment, especially when they met later that night. “I genuinely had no clue until after the show that I appeared on screen until we were out in Lillie’s Bordello and people were saying they’d seen me,” she added, laughing at the memory.
Despite the teasing, Molly-Kate has taken the viral fame in stride. She said she is happy that her candid reaction brought joy to others, even if at her own expense. “I couldn’t believe it,” she admitted. “People got a smile out of it, which is funny.”
The charm of the moment lies in its honesty. Molly-Kate’s visible disappointment perfectly captured what many fans might have felt in her position, making her instantly relatable. Her reaction stood in stark contrast to the usual polished responses expected on television, which may explain why it spread so quickly online.
For Daniel O’Donnell, a household name in Ireland for decades, the incident highlights the depth of affection his fans have for him. The audience’s excitement at the prospect of seeing him—even if it turned out to be an impersonation—demonstrates just how deeply he is loved across generations. Rosenstock’s impression, meanwhile, was another reminder of his skill at capturing the mannerisms of Ireland’s best-known figures, even if it caused momentary heartbreak for at least one dedicated fan.
The viral clip also underscores how quickly small moments on live television can capture the public imagination in today’s digital age. Just a few seconds of genuine human emotion were enough to propel Molly-Kate into the spotlight, creating a wave of memes, shares, and laughter across the internet.
Yet at the heart of the story is something simple and endearing: a fan’s unfiltered love for her idol. Molly-Kate’s joy at the thought of seeing Daniel O’Donnell, followed by her comic disappointment, resonates because it reflects the emotional connection people feel with the artists who soundtrack their lives.
In the end, what could have been just another comic sketch on The Late Late Show has turned into a memorable piece of Irish television history. And for Molly-Kate, while the teasing from friends may continue, she now holds a unique place in the world of Daniel O’Donnell fandom—known not just for her devotion but for a reaction that brought laughter to thousands.
As she put it herself, the fact that people could smile at her expression makes it worthwhile. In an era where viral moments can be fleeting and sometimes cruel, this one feels refreshingly human, heartfelt, and humorous—a reminder that sometimes, the most genuine reactions are the ones that touch us the most.
