I'm assuming they get to practice this week but the "random" one, I dont get

I havent found out any other information.

I love Ruben's voice. It's the Motown booty girl in me. But Clay can so do the schmooozing involved - the PR stuff. AND he can sing - he is almost flawless in his performances.

Last year, didnt the final 2 (Justin & Kelly) do a duet together?

Ladies and Gentlemen: Ruben and Clay singing:

Ebony and Ivory

Islands in the Stream

Leather and Lace

I Got You Babe

Endless Love
