The 20 Best Carpool Karaoke Episodes, Ranked

From Mariah Carey to Harry Styles to Adele to Michelle Obama, the best, most memorable musical segments on The Late Late Show with James Corden

Mimi is having none of it. She calls out Corden for his "act," looks like she'd rather be anywhere else and gives the disclaimer: "I'm not singing today, I've been up all night." The chanteuse relents, and lends her incredible pipes to join in on "Vision of Love" and other songs, and urges Corden to try his hand at his best New York accent. Hint: It's not great.
