Michelle Obama showed us once again why we're going to miss her so much when she leaves the White House. She joined James Corden on The Late Late Show for his popular "Carpool Karaoke."

After trading jokes with Corden about President Obama's whereabouts—"he better be" in the White House, she lobbed, "that's where he said he was"—she got down to business, singing Stevie Wonder's classic, "Signed, Sealed, Delivered."

She lamented that she doesn't get to rock out to music in the car often since she rarely rides in the passenger seat anymore, you know, being the first lady and all, so she was especially excited.

She bounced around to Beyoncé's hit, "Single Ladies" next, (although we would've to have seen her perform Bey's "Formation" for obvious reasons). Either way, she knew the words and the hand movements to the song, and in true Michelle Obama fashion, it was awesome. She even joked about the Beyhive.

"We were makin' honey to put in our Lemonade," she laughed, before explaining why she recently got on SnapChat. It's about an education empowerment initiative for young girls worldwide, FYI.

Corden and Obama were then joined by Missy Elliott who sang her girl power song, "This Is For My Girls," from the backseat. But one of the coolest moments of the segment came when they went into Missy's "Get Ur Freak On," which Michelle knew most of the words to. Seriously, how is she not the coolest first lady of all-time?
