Kate Hudson and Hugh Jackman have sparked fresh buzz online after a behind-the-scenes moment showed the two stars belting out a drunken karaoke duet to a Neil Diamond classic, sending fans into a frenzy over their natural, electric chemistry.
The clip, playful and unpolished, felt less like a rehearsed publicity moment and more like two people genuinely enjoying the music — a vibe that perfectly mirrors their on-screen connection in the new romantic drama Song Sung Blue.
The film, released on Christmas Day in the U.S. and New Year’s Day in the UK, stars Hudson and Jackman as Claire and Mike Sardina, a real-life couple who found unexpected fame as the Neil Diamond tribute duo Lightning & Thunder.
Their easy rapport, both on and off camera, has been widely praised by fans, many of whom say the pair felt “so real” that they forgot they were watching actors. One viewer summed it up perfectly, writing that Hudson and Jackman were “so genuine they seemed like real people — and the singing was incredibly entertaining.”
That authenticity has become one of the film’s biggest talking points. Social media is filled with emotional reactions from audiences who say the movie made them laugh, cry, sing along, and even return to theaters for repeat viewings. Several fans have called it one of the most uplifting films of the year, applauding Hudson’s transformation into Claire and Jackman’s heartfelt performance as Mike.
However, the film has not been without controversy. Michael Sardina Jr., the real-life son of Mike Sardina, has publicly criticized the movie, calling it “all lies” and claiming his father would be “rolling in his grave.”
While Claire Sardina has fully supported the project, both Michael Jr. and his sister Angelina have expressed frustration over what they describe as inaccuracies and omissions in the story. Neither Hudson, Jackman, nor the film’s producers have responded to the claims.
Despite the backlash, the karaoke moment has only fueled affection for the film and its stars. Fans praised the decision to include the real-life “Thunder” in the movie’s promotion, calling it a touching and respectful nod to the true story behind the music. As one commenter wrote, “They did a terrific job portraying Lightning and Thunder — it felt honest, emotional, and full of heart.”
Whether singing on screen or laughing through a karaoke performance off it, Kate Hudson and Hugh Jackman have clearly struck a chord. And for many fans, that raw, human connection is exactly what makes Song Sung Blue resonate long after the final note fades.
