Final four perform for last time before 'Voice' finale

UNDATED (WHDH) -- The final four “Voice” contestants had three chances to sing their best before Tuesday night's finale. Now, it's up to America to decide their fate.

Each singer got an individual performance, a duet with their coach, and a tribute song -- their take on one of their coach's hits.

While the night was a celebration of talent, it wasn't without a little controversy.

With America’s vote on the line, Jermaine Paul and Team Blake did not hold back.

Tony Lucca, 36, had a unique take on Jay-Z’s "99 Problems" that fired up a feud between Lucca's fellow former Mousekateer Christina Aguilera and his coach, Adam Levine.

"The lyrical connotation was a little derogatory toward women," said Aguilera.

Aguilera got the last word on stage with Chris Mann in a powerhouse duet. In his individual performance, Mann brought Aguilera to tears.

Juliet Simms brought down the house with coach Cee Lo Green, and then rocked out on her own.

America now votes on the individual performances only, and this time, the coaches have no influence on the vote.
