James Corden welcomed an extra special Carpool Karaoke participate Wednesday (July 20) in the form of first lady Michelle Obama. She may not have her own catalogue of music to sing along with, but she's more than willing to rock out to her favorite artists, like Stevie Wonder and Beyonce.

When he first picks up her, Corden asks her, "What are you going to miss? And what are you accidentally going to slip into your bag? ... Because I've only been here five minutes and I've got my eye on a couple of bits."

"Don't steal anything!" says the first lady, to which Corden protests, "I'm not gonna steal it, I'm going to forget it was in my pocket. That is a very different thing."

He also wonders if she's going to miss 24-hour room service, like calling down for a milkshake and a grilled cheese at 3 a.m.

"That's nice, but the freedom that we'll get in exchange for the privileges and the luxuries ... seven-and-a-half years, that's enough. I can make my own grilled cheese," says Obama.

Next it's time for Beyonce's "Single Ladies," of which Obama knows all the words and dance moves. Afterward, she quips, "We were making honey in the Bey hive. We were making honey to put in our lemonade!"

The first lady, she's got jokes.

Now, lest you think Michelle Obama doesn't have any songs of her own, that's not entirely true. The next jam is "This Is for My Girls," the charity anthem she released that was written by Diane Warren and features the vocal stylings of Kelly Clarkson, Kelly Rowland, Zendaya, Janelle Monae, Lea Michele, Missy Elliot, Chloe and Halle and Jadagrace. And as luck would have it, Missy Elliot is there to join in the Carpool Karaoke fun.

So they can't let Missy leave without singing one of her songs too -- who knew the first lady of the United States knew all the words "Get Ur Freak On"?
