Ariana Grande, Ben Stiller and Robert De Niro gave The Tonight Show Starring Jimmy Fallon a Christmas detour on Sunday, November 8. The Focker-in-Law co-stars interrupted Fallon’s monologue with “O Christmas Tree” to promote their upcoming film, according to Deadline and Variety. SourceSource
Fallon supplied the cue: “The holidays are coming. The spirit’s here. It kinda makes me wanna sing,” he said, according to Variety. Grande’s answer was “We can help with that!” The number ended with De Niro lip-syncing to a melodramatic operatic voice, the outlet reports. Source
The evening also gave Grande a chance to test her co-stars’ lie detectors. During “True Confessions,” she convinced Fallon, Stiller and De Niro that a made-up story about falling into an aquarium fish tank as a child was true, Variety reports. Source
The guests also joined Fallon in a pre-taped soap-opera parody called “My Family’s Money,” with characters slow-clapping while delivering their lines, according to Variety. Between the opera lip-sync and the dramatic applause, nobody was rationing the theatrics.
