On Monday, "The Voice" contestants brought their A-game to the knockout rounds, leaving the coaches with some tough decisions to make.

But among the amazing singers who took the stage, there were two standout performances ... both from Cee Lo Green’s team.  

Trevin Hunte, 17, who’s definitely been a fan fave in the competition, covered  Phill Collins' "Against All Odds" … and he killed it!

Go to 1:43 to see Trevin's performance.

But the performance of the night belonged to Mackenzie Bourg, 19, who transformed Carly Rae Jepsen's pop-anthem, "Call Me Maybe." Bourg's version is almost unrecognizable compared to Jepsen's ... sounding closer to a Jason Mraz tune!

Check out Mackenzie cover of the song below.

Which of the coaches do you think has the strongest team, Adam Levine, Christina Aguilera, Blake Shelton or Cee Lo Green? Sound off below!
