Jennifer Love Hewitt can't stop dancing to Jamie Miller's viral hit 'Babydoll.' She's not alone.

There are only so many times a singer can post himself dancing to the same song before people start scrolling past. Jamie Miller seems to have found a way to fix that: by bringing in celebrity dance partners.

The Welsh singer has been promoting his infectious new song, "Babydoll," on TikTok and Instagram by two-stepping to the track in video after video. Lately, though, the people dancing alongside him have gotten a lot more recognizable. Jennifer Love Hewitt was the first famous face to join him. Dancing With the Stars ' Julianne Hough then followed, as did Antonio Cipriano , one of the breakout stars of Prime Video's series Off Campus .

Love Hewitt, in particular, really got into "Babydoll," using it in several TikToks and posting a video of herself playing it on the piano. "Playing around with it makes me smile," she wrote in the Aug. 12 post, thanking Miller for the song. Just days later, she was dancing alongside him , with Miller dubbing her "the most iconic babydoll there is."

The upbeat track was released Aug. 7, although Miller had been teasing it by posting snippets since late July. Now, each new "Babydoll" video comes with a question: Who will Miller get to join him next? Viral dances can come and go quickly, but rotating cameos give the same song a reason to keep popping up on people's feeds: it's the ideal formula for keeping a viral moment going.

Singer Role Model pulled off something similar with his track "Sally, When the Wine Runs Out," bringing a different "Sally" onstage during performances. Celebrities including Natalie Portman, Olivia Rodrigo and Charli xcx all took a turn, and clips of the cameos routinely went viral. Finding out who Sally would be became part of the attraction.

Sabrina Carpenter put her spin on the celebrity reveal during her Short n' Sweet tour, jokingly "arresting" famous faces for "being too hot" before singing "Juno." Millie Bobby Brown, Gigi Hadid and Salma Hayek were among those who got cuffed.

For anyone just discovering Miller through "Babydoll," he's been around for a while. The 28-year-old appeared on The Voice U.K. in 2017, where he competed on Jennifer Hudson's team and finished third. He released his debut album, titled Long Way Home , in 2024, but it did not chart on the Billboard 200.

Earlier this year, he signed with Republic Records , which is home to many of pop's biggest names, including Taylor Swift, Ariana Grande and the Weeknd. He has a sizable social media fanbase, including 4.1 million followers on TikTok and 1.2 million on Instagram — but "Babydoll" has put a new level of attention on the singer.

Love Hewitt has been posting about "Babydoll" enough that people have started wondering if she's on the record company's payroll. "People have asked me, 'Why are you putting it in all of your videos, besides the fact that it's addicting? Why are you pushing this song so much? Do you work for his record company?'" she said in a TikTok posted Aug. 23.

Love Hewitt clarified that she didn't work for his record company and said she first heard "Babydoll" on a day that "was not great." "Music finds you when you really need it," she said, and the song changed her mood: "The day was instantly better, more manageable, full of light."

Then she got to know Miller. "He is light. He is magic," the actor said. The first time they met in person was when they filmed their video together. Love Hewitt is clearly rooting for him now. "He is such a pure, kind, good human, who has worked so hard for this moment," she said. "We are all collectively gathering around him, rooting for him, becoming his magical, positive light army in the world."

How long the "Babydoll" moment lasts is anyone's guess. But for now, Miller has something plenty of singers would envy: a growing audience waiting to see what happens next.
