Just in case you need another reason why Michelle Obama is our coolest First Lady ever- here’s the billionth one!

FLOTUS  joined James Corden for “Carpool Karaoke.”  And just in case you haven’t seen this show, its pretty funny. Celebrities ride around with the comedian and talk-show host and karaoke to their favorite songs.

The two drove around the White House grounds singing  Stevie Wonder’s “Signed, Sealed, Delivered I’m Yours” and Beyonce’s “Single Ladies.”They talked about everything from the Beyhive and Lemonade to Michelle’s Snapchat ( which is on fleek, please add her: michelleobama) . She also shared her and hubby, President Obama’s secret service codes names (Renaissance and Renegade, shh).

Near the end, Missy Elliot popped up in the back seat to join in for “This Is for My Girls,” a girl power anthem Missy wrote to promote the First Lady’s “Let Girls Learn” initiative.  And its not a complete car ride with Missy unless you  turn-up to her 2001 hit, “Get Ur Freak On.”

The “Carpool Karaoke” was taped last month. It aired Wednesday night on The Late, Late Show on CBS.
