Bursting with energy and flawlessly blending Latin flair with modern pop, the routine became one of the most visually stunning and electrifying openings of the show’s “new era.” The audience could hardly believe their eyes—who knew the hosts could bring the heat like that?

The confetti had barely settled from the Season 34 premiere’s explosive kickoff when the ballroom at ABC’s El Capitan Theatre in Los Angeles erupted into a frenzy unlike any in the show’s 20-year history. It was September 16, 2025, and Dancing with the Stars — fresh off the record-breaking triumph of Season 33, where Bachelor heartthrob Joey Graziadei and pro Jenna Johnson claimed the Mirrorball — was pulling out all the stops for its milestone anniversary. Co-hosts Alfonso Ribeiro and Julianne Hough, the dynamic duo who’d helmed the series since 2022, stepped out not in their signature sparkling suits and gowns, but in fire-engine red and black ensembles that screamed “pro dancer” more than “emcee.” What followed was a seismic shift: for the first time ever, the hosts ditched the microphone stands to deliver a full-throttle Cha-Cha-Cha to Jennifer Lopez’s “Let’s Get Loud” — a pulsating anthem that had the crowd on their feet before the first verse even hit.

Picture this: The lights dim to a sultry crimson haze, the live band led by the legendary Ray Chew strikes up those iconic brass blasts, and out glide Hough and Ribeiro, hips popping in perfect sync. Julianne, 37, the two-time Mirrorball winner from her pro days (Seasons 5 and 19), moved like liquid fire — her extensions sharp as a stiletto, her spins a whirlwind of blonde hair and sequins. Alfonso, 53, the Season 19 champ whose Carlton Banks legacy still owns TikTok, matched her beat for beat, his footwork a masterclass in Cuban motion that recalled his viral DWTS freestyle. They weren’t just dancing; they were channeling J.Lo herself, infusing the routine with streetwise salsa flair — quick-quick-slow steps that built to a feverish bridge where they traded playful lifts and dips, their chemistry crackling like static. The backdrop? A massive LED wall pulsing with urban graffiti and fireworks, symbolizing the show’s evolution from staid ballroom to boundary-pushing spectacle.

The audience — a starry mix of Season 33 alums like Graziadei and Ilona Maher, plus fresh faces from the 14-celeb cast including Hilaria Baldwin, Olympic gymnast Jordan Chiles, and comedian Andy Richter — lost it. Screams drowned out the horns; phones shot up like a forest of lighters at a rock concert. “Is this real life?” one viewer tweeted mid-air, the clip already racking up 2 million views on X within minutes. Judges Derek Hough (Julianne’s brother and a four-time champ), Carrie Ann Inaba, and Bruno Tonioli leaped from their panel, Derek pumping his fist in sibling pride, Bruno yelling, “Mamma mia, that’s-a spicy meatball!” over the applause. Inaba, returning after missing the premiere due to illness, wiped away tears: “You’ve just set the bar stratospheric.”

This wasn’t mere opener fodder; it was a deliberate reinvention. Showrunners Tyce Diorio and Mandy Moore, who choreographed the number, drew inspiration from the series’ 20th anniversary — a nod to its 2005 debut under Tom Bergeron — while honoring the “new era” ushered in by Disney’s streaming synergy and live dual-airing on ABC and Disney+. “We wanted the hosts to embody the magic,” Moore told Variety post-taping. “Alfonso and Julianne aren’t just presenters; they’re living legends. Why not let them remind everyone why?” The choice of “Let’s Get Loud” — J.Lo’s 1999 Bronx-born banger — amplified the theme, echoing the cast’s “personal anthems” night where celebs like Baldwin (with Gleb Savchenko) reprised it for her own Cha-Cha later that episode. It was meta magic: hosts priming the pump for the pros and stars, blurring lines between stage and spotlight.

Behind the sequins, the prep was Herculean. Ribeiro, juggling America’s Funniest Home Videos and his Ribeiro Family Foundation’s post-hurricane relief drives in the Carolinas, logged 40 hours of rehearsals in a private L.A. studio. “Julianne’s a beast,” he laughed in a pre-premiere People interview. “She’s got that Hough precision — I’m just trying not to trip over my own feet like Carlton at a wedding.” Hough, who stepped away from judging in 2023 to focus on producing her Troubadour Broadway residency, admitted nerves: “Hosting lets me breathe, but dancing? It’s like riding a bike — if the bike’s on fire.” Their bond, forged in Season 19’s finals, fueled the fire; off-camera, they’d FaceTime choreo tweaks, with Ribeiro’s kids crashing calls for impromptu critiques. The result? A routine that clocked 3 minutes of pure adrenaline, ending in a dramatic dip where Ribeiro “dropped” Hough — only for her to flip upright into a triumphant pose, arms flung skyward as pyrotechnics exploded.

Social media crowned it instant icon status. #DWTSHostsDance trended worldwide, spawning edits layering the Cha-Cha over J.Lo’s Super Bowl halftime. Fans raved: “Alfonso’s hips don’t lie — Shakira who?” while one viral thread dissected the footwork: “That’s New York hustle meets Latin heat. 10/10, would rewind.” Even Lopez herself chimed in on Instagram: “Y’all turned my song into pure fuego! Bronx pride in the ballroom. 💃🕺” Cameos amplified the buzz — troupe dancers like Britt Stewart and Pasha Pashkov joined for a mid-routine breakdown, while guest Mark Ballas (back from retirement) hyped from the wings. Ratings soared: The premiere drew 8.2 million viewers, a 15% bump from Season 33, with the opening segment alone spiking 22% in the 18-49 demo.

For Ribeiro and Hough, this was personal triumph amid a whirlwind year. Ribeiro, fresh from his off-ballroom heroics — rescuing 47 shelter dogs in L.A. and that unifying “God Bless America” moment at Madison Square Garden — infused the dance with his signature joy. “Life’s too short not to move,” he posted post-show, a behind-the-scenes reel showing him practicing lifts with a giggling Ava Sue. Hough, navigating her directorial debut on a Vogue docuseries, saw it as reclamation: “I left the floor to grow, but damn, it feels good to groove again.” Their performance didn’t just electrify; it humanized the hosts, proving star power thrives in sweat and sync.

As the night unfolded — with standouts like Chiles’ gravity-defying Paso Doble and Richter’s comedic Jive — the Cha-Cha lingered like glitter dust. It set a tone for Season 34’s twists: celebrity-led relays with Mirrorball vets, a Tom Bergeron guest spot, and pro numbers choreographed by Derek Hough himself. In a landscape of reboots and realities, DWTS reminded us: The best openings aren’t scripted — they’re sparked. Hough and Ribeiro didn’t just transform; they transported the ballroom back to its roots, louder, prouder, and unapologetically alive. Who knew the emcees could steal the show? Everyone — now.
