Ariana Grande Sings O Christmas Tree With Robert De Niro & Ben Stiller on Tonight Show: Exclusive Preview

Ariana Grande and her Focker-in-Law co-stars Robert De Niro and Ben Stiller are a Christmas caroling trio in a special preview clip from NBC’s The Tonight Show Starring Jimmy Fallon, premiering here on Billboard just ahead of a special Sunday night (Nov. 8) episode of the late-night show beginning at 11:35 p.m. ET.

Fallon celebrates this weekend’s arrival of the 2026 Rockefeller Center Christmas tree on tonight’s episode. The Focker-in-Law stars join in on the festivities with a surprise performance of the traditional tune “O Christmas Tree.”

Grande takes the lead on vocals, of course, and the audience can’t help but applaud when she hits those high notes. Stiller gives a valiant effort for his part of the song, and De Niro — well, it’s worth tuning in to the sneak peek below to see how it all plays out.

Grande, De Niro and Stiller will be chatting together with Fallon throughout Sunday’s episode, which also features Lil Baby as musical guest. The fun begins after the Buccaneers vs. Bears game on NBC.

The stars’ appearance together is part of their promo cycle for the Nov. 25 theatrical release of Focker-in-Law, the latest movie in the popular Meet the Parents franchise. Grande joins as Olivia Jones, who’s dating Greg and Pam Focker’s (Stiller and Teri Polo) now grown-up son Henry (Skyler Gisondo).

The Nov. 8 Tonight Show episode is the second of four special episodes to air following NBC’s Sunday Night Football broadcasts this season; the first special broadcast was on Sept. 27, with guests Sylvester Stallone and Luke Bryan.

Tonight’s Focker-in-Law cast takeover with Grande, De Niro and Stiller (plus Lil Baby) will be followed by an episode featuring Jennifer Lopez and Anthony Mackie, as well as a musical performance from Quavo, on Sunday, Nov. 15. Another post-Sunday Night Football episode of The Tonight Show is slated for Jan. 10, with guests to be announced.
