For Michelle Obama, riding in the front seat of a car is a rare occurrence. So it's understandable why she was enthusiastic about slipping into a minivan with James Corden, host of "The Late Late Show," and belting out a few tunes.

In a video that aired Wednesday night — and has already garnered roughly 2.3 million views — the pair drive in circles around the South Lawn and sing along to Stevie Wonder's "Signed, Sealed, Delivered," Beyonce's "All the Single Ladies" and other songs with gusto. In between the singing — which includes a guest appearance by rapper Missy Elliott — Obama and Corden discuss everything from Snapchat, children's education and the first family's Secret Service code names.

And the first lady disclosed the tiniest bit of news — this wasn't the first time she's ridden shotgun since moving into the White House.

“I’ve been in a car, maybe it was months ago, with my daughter, who learned to drive, and we rocked out a little, we rocked out with her," she said. "But that’s the only time in seven-and-a-half years that I’ve been in the passenger seat, listening to music, rocking out like this. So this is a treat!”

An aide said in an email Thursday that "we won’t be able to give you any additional details beyond what the first lady said" about the time she "rocked out" with Malia at the wheel.

Now, the first lady is on record as saying the U.S. Secret Service made the decision that it — not she or the president — would teach Malia how to drive, given security concerns.

But Malia does occasionally drive on her own.

"Driving, for Malia, I think, gives her a sense of normalcy, like the rest of her friends are doing," the first lady said on "Live! With Kelly and Michael" in April 2015. "And my kids have got to learn how to live in the world like normal kids."

And at least one time, apparently, she persuaded her mother to come along for the ride.
