James Corden is back at it again with the second episode of Carpool Karaoke: The Series [1], and this time he has two of the biggest and most beautiful voices in his car: Alicia Keys [2] and John Legend [3]. However, instead of singing their smash hits during the ride, The Late Late Show [4] host had them make up songs on the spot about the weirdest things. While Alicia blows us away with her melody about bad body odor, John's soulful tune about a long-lasting erection is surprisingly incredibly sexy. Catch all the craziness above, and watch the full episode on Apple Music.
