Watch Michelle Obama and James Corden Sing 'Get Ur Freak On' with Missy Elliott on 'Carpool Karaoke'

On its way to becoming a cultural juggernaut, James Corden's "Carpool Karaoke" segment on The Late Late Show has swept up the Red Hot Chili Peppers, Adele, Mariah Carey, Justin Bieber and a laundry-list of other icons. 

The next logical step for Corden and company came on Wednesday night, when the talk show host pulled up to the frickin' White House to pick up first lady Michelle Obama.
