The latest: Ariana Grande leads impromptu holiday choir on Tonight Show stage

November 9, 2026 · New York.

Pop superstar Ariana Grande temporarily broke her hiatus from live performance on Sunday evening, blindsiding The Tonight Show audience by marching onto the stage mid-monologue alongside Hollywood heavyweights Ben Stiller and Robert De Niro.

The unannounced stunt, staged during a special post-football telecast at NBC's Studio 6B in Rockefeller Center, kicked off the official promotional campaign for Universal Pictures' upcoming holiday comedy Focker-in-Law—the fourth installment in the blockbuster Meet the Parents franchise. As host Jimmy Fallon attempted to deliver his opening monologue jokes, Grande, Stiller, and De Niro strode out in coordinated velvet suits, taking over Fallon's microphone to lead the 300-person studio audience in an impromptu chorus of "O Christmas Tree."

The appearance marked Grande's first major public appearance following the cinematic release of Wicked, showcasing her return to comedic acting opposite two of Hollywood's most revered comedic titans.

How Grande, Stiller, and De Niro blindsided Fallon during Sunday broadcast

The comedic hijacking began three minutes into Fallon's monologue when Stiller walked briskly past the house band, The Roots, waving his arms to halt the monologue setup. Before Fallon could respond, De Niro followed closely behind with his trademark furrowed stare, deadpanning that late-night television needed "more gravitas and earlier holiday spirit."

Moments later, Grande emerged from the iconic blue backstage curtain to a deafening standing ovation from the crowd. Grabbing a handheld microphone, she harmonized over Stiller and De Niro's comically unpolished vocals before playfully ushering Fallon to his desk to start the interview segment prematurely.

During the sit-down interview, Stiller revealed that the trio had concealed themselves in the building's green rooms since late afternoon, rehearsing the surprise hijacking in secret to ensure genuine shock from the audience.

Stepping into the Focker universe: Grande's first major post-Wicked comedy

Directed by original franchise helmer Jay Roach, Focker-in-Law picks up over fifteen years after Little Fockers, focusing on the chaotic nuptials of Greg and Pam Focker's adult son, Henry. Grande portrays Olivia Jones, an accomplished opera singer from an eccentric New England family whose unconventional lifestyle clashes violently with the strict, suspicious worldview of retired CIA operative Jack Byrnes, played once again by De Niro.

Grande shared behind-the-scenes stories about filming an elaborate Thanksgiving dinner sequence where her character attempts to perform the Heimlich maneuver on De Niro's character after he chokes on a turkey bone.

"I was terrified that I was actually going to hurt an American cinema legend on my second day on set," Grande joked. "Bob looked at me in the middle of a take, stayed completely in character as Jack Byrnes, and whispered: 'Push harder, kid, you're not going to break me.' It was easily the most surreal afternoon of my acting life."

The stars later participated in the popular Tonight Show parlor game "True Confessions" and performed in a melodramatic sketch titled "Slow Clap Soap Opera," which went viral across social platforms within hours of airing.
