(CBS News) The final four "Voice" contestants have hit the final stretch of the singing competition - all in hopes of landing a recording contract.

Tony Lucca, Chris Mann, Jermaine Paul and Juliet Simms battle it out Monday night, each performing a solo song, as well as a duet with their coaches.

The second season winner will be announced in a two-hour finale on Tuesday, which will also include a star-studded list of music guests. Lady Antebellum, Flo Rida and Hall & Oates will perform. Justin Bieber is expected to sing his latest single, "Boyfriend."

So who will it take home this year's prize? Lucca for Team Adam Levine? Paul with Team Blake Shelton? Mann with Team Christina Aguilera, or Simms with Team Cee Lo Green?

This year's contestants have interesting backgrounds. Lucca starred on the "Mickey Mouse Club" with Aguilera, while Paul used to be a back-up singer for Alicia Keys.

"The Voice" executive producer Mark Burnett told USA Today, "You have no idea who's going to win. From the blind auditions last year, there were a lot of people thinking that possibly (eventual winner Javier Colon) was going to win it. This year, I could see every reason any of them could win."

"The Voice" airs Monday at 8 p.m. ET/PT. The Tuesday finale begins at 9 p.m. ET/PT on NBC.
