'Duets': What happened to John Legend's partner Johnny Gray?

• I promise you bro, if I had been on this week, I would have been #1, GUARANTEE! Did they explain why I'm gone? #Duets

Last week, he and Legend performed "Ordinary People" and while it wasn't our favorite duet of the night, the judges really liked it and they put Johnny in second place on the leaderboard and there he stayed throughout the night. Video below of their performance.

Meanwhile, Legend had to conduct an on-the-fly audition for a new partner and ended up with Meleana Brown from Oahu, Hawaii, with whom he performed the classic duet "Endless Love" this week. We thought she was a worthy replacement - Meleana has a gorgeous voice. 

What do you think, "Duets" fans?
