Congratulations!Christian and Nicolina's performance stuns judges, Lionel Richie makes interesting decisionWhen Christian Guardino and Nicolina Bozzo took to the stage, the latter revealed that they would be performing Andrea Bocelli and Celine Dion's The Prayer. View this post on Instagram Instagram PostThe vocalists alternated between different vocal ranges, synchronizing in harmony throughout. During their heightened harmonies, other contestants even stood up and applauded them. As they ended their performance with a hug, the judges were left speechless. Lionel Richie was thoroughly impressed with the duo and said:“I have to tell you, when you can stand on a stage under pressure, and we’re mesmerized just watching how you play off each other, it has all the makings of something so special. You’re growing.”When it came to picking a winner, the judges struggled to pick one over the other. It ultimately came down to Richie. He said:"We have to break it down to who goes forward and who goes back. When you have a duel, somebody gets shot. When you have voices of this power, it’s who cut through. I think it’s quite obvious - you both cut through. You’re both going to the next round."
