Ariana Grande & Jeff Goldblum Drop a Surprise Jazz Duet – “I Don’t Know Why (I Just Do)” Explained

Ariana Grande and Jeff Goldblum might sound like an unlikely duo, but their new jazz collaboration, “I Don’t Know Why (I Just Do),” is smooth, soulful, and seriously charming. Released as part of Goldblum’s new album Still Blooming, the track showcases the best of both worlds—Ariana’s ethereal vocals and Goldblum’s vintage jazz vibes.

If you’re wondering how this magical crossover happened (and what makes the song so special), we’ve got all the details below—including lyrics, musical breakdown, and the sweet Wicked-inspired backstory.


🎹 How Did This Collab Even Happen?

Believe it or not, this team-up was born on the set of Wicked, where Ariana Grande plays Glinda and Jeff Goldblum plays the Wizard. According to Goldblum himself, the track came out of a “special connection” between the two stars while filming. And honestly? You can feel that chemistry in every note.

Jeff Goldblum isn’t just a beloved actor—he’s also a seasoned jazz musician. With his band, The Mildred Snitzer Orchestra, he’s been blending classic jazz with Hollywood flair for years now. Still Blooming, his latest album, features a mix of standards with guest vocalists—and Ariana’s feature is easily a standout.

🎶 About the Song: “I Don’t Know Why (I Just Do)”

Originally written in 1931, "I Don’t Know Why (I Just Do)" is a timeless jazz standard covered by legends like Dean Martin and Ella Fitzgerald. But Ariana Grande’s version gives it a fresh breath of air.

Why It Works:

  • Minimalist arrangement: Just piano, soft brass, and subtle rhythm. The production leaves space for emotion.

  • Ariana’s voice: Her silky, breathy delivery fits jazz perfectly—less pop diva, more vintage lounge singer.

  • Goldblum’s piano playing: Gentle and expressive, he sets the tone without stealing the spotlight.

It’s a romantic, melancholic little number that feels like a dreamy detour from Ariana’s usual sound—and we’re here for it.


🧚 The Wicked Connection

While Wicked is set to release soon, fans are already loving the dynamic between Ariana and Jeff behind the scenes. This collab is a musical appetizer for their onscreen chemistry. And let’s be honest, this track kind of feels like something the Wizard and Glinda might slow dance to in an alternate universe.

Could this lead to more music together? Maybe a jazzy duet in the movie soundtrack? We’re not saying it will happen… but we’re definitely hoping.


📜 Lyrics – “I Don’t Know Why (I Just Do)” (Ft. Ariana Grande)

Here’s the full lyrics to the track so you can sing (or swoon) along:

I don’t know why I love you like I do
I don’t know why, I just do
I don’t know why you thrill me like you do
I don’t know why, you just do

You never seem to want my romance
The only time you hold me is when we’re dancin’

I don’t know why I love you like I do
I don’t know why, I just do

(repeats with slight variations)
I don’t know why, I just know

Simple, sweet, and surprisingly haunting.
