James Corden got a little more than he bargained for when he showed up at the White House for a "tour."

On Wednesday's episode of The Late Late Show, Corden debuted a new edition of Carpool Karaoke with First Lady Michelle Obama. The pair dueted on Stevie Wonder's "Signed, Sealed, Delivered" and Beyonce's "Single Ladies," before being joined by Missy Elliott to perform her hit "Get Ur Freak On" and Obama's Let Girls Learn initiative's power anthem, "This Is for My Girls," on which the rapper is featured.

The first lady said it was only the second time she's been in the passenger seat of a vehicle "rocking out" since President Obama was sworn in. (The first time was when their daughter Malia was learning how to drive.)
