Carpool Karaoke is a recurring segment on The Late Late Show with James Corden, in which host James Corden invites famous musical guests to sing along to their songs with him whilst traveling in a car driven by Corden on a planned route usually in Los Angeles, usually under the pretense of needing to get to work and preferring to use the high-occupancy carpool vehicle lane, or the pretext of needing directions from a local when in a new town, such as London, Liverpool, New York City or Las Vegas.
