Alicia Keys, James Corden catch a ride with John Legend for 'Carpool Karaoke'

When you've got the right Keys, anything can sound like a Legend. 

At least that was the idea when Alicia Keys and John Legend joined James Corden for a round of Carpool Karaoke. 

In the episode released by Apple Music Tuesday, Corden asked the singers to put their own musical spin on a variety of random phrases. 

The first" "Do you need a lift, bro?" After thinking it over, Legend broke into a fun jam. Keys also chimed in with her own harmonies. 

The next was interesting: "Natural deodorant makes promises it just can't keep." Before launching into her rendition, Keys shared that she uses natural deodorant. 

"Me and my husband, we talk about this all the time," she said. "Anytime he asks to borrow my deodorant, he is so upset at me at the end of the day." 

Billy Eichner and Metallica also hopped in the car (sans Corden) in another episode released Tuesday. 

Eichner suggested he and the band play a game called "Metal Have I Ever," a spinoff of "Never Have I Ever." 

"Metal Have I Ever been excited about a new flavor of yogurt -- are you guys yogurt people?" Eichner asked. 

Turns out ,Metallica loves frozen yogurt. 

Eichner also sang Part of Your World from The Little Mermaid, and after a few bars, James Hetfield joined in. 

New Carpool Karaoke episodes are available weekly on Apple Music.
