The season finale of ABC's 'Duets' is tonight (July 19), with Sugarland's Jennifer Nettles landing both of her singers inside the Top 3. John Glosson and J Rome will square off against Kelly Clarkson's singer Jason Furol, and then viewers will decide the winner. Who do you think should win 'Duets'?

J Rome has out-performed Glosson and Furol on a weekly basis, but the other two have become fan favorites. If we've learned one thing about similar reality television shows, it's that the best singer doesn't always win if he or she doesn't connect with the audience. Robin Thicke and John Legend will take part in the opening performance and in critiquing the three last-standing 'Duets' finalists.
