Who Should Win The Voice?

And then there were four!

America saw Jermaine Paul, Chris Mann, Juliet Simms and Tony Lucca sing for this season's title on Monday's performance round, and on Tuesday's grand finale, viewer votes will determine which singer will walk away with that coveted record contract.

After the singers delivered their Monday night performances, Voice coaches Blake Shelton and Adam Levine took to Twitter to drum up support for their favorites.

"Oprah just released a statement saying that if @JermainePaul wins The Voice children are more likely to learn how to read!!" Shelton tweeted of his singer Paul.

Argued Levine, who was forced to defend Lucca after Christina Aguilera slammed his "99 Problems" performance: "If my iTunes account could talk, it would say, "really Adam? You really wanna purchase @Luccadoes single again?" #YESPLEASE"

If iTunes downloads are any indication going into Tuesday's finale, Aguilera's comments failed to sway Lucca fans, as the former Mickey Mouse Club star's Voice performance was the third most downloaded track overnight.

Simms' "Free Bird" ranked ninth in the iTunes top 10 as of Tuesday afternoon.
