Somebody had to go home on Thursday’s The X Factor results show, but it most certainly wasn’t going to be Alex & Sierra.
America voted to send the pair – who wowed the judges Wednesday night with their flawless rendition of Sara Bareilles’ “Gravity” – through to next week’s finale.
“We just want to thank everybody that’s voted. This is incredible,” a humble Alex said upon hearing the news, while the group’s mentor, Simon Cowell, gushed about the talented singers.
“I think they’ve been incredible to work with,” he said. “They’ve gotten better every single week and the finale would not be the same without them.”
Host Mario Lopez then asked them to perform a song in what he called their “campaign to win.”
The singers chose the Passenger’s “Let Her Go” and delivered what may be their most beautiful performance on the show all season.
Carlito Olivero – aka the most excited contestant to advance to the finals in the history of reality singing competitions – chose Elvis Crespo’s “Suavemente” as his “campaign to win” song.
“You just made my dream come true!” the singer said upon hearing the happy news. “I love y’all so much!”
The final contestant to be put through to the finals was Jeff Gutt, whose electrifying performance of Journey’s “Open Arms” is the biggest threat to Alex & Sierra’s chances of winning the million-dollar recording contract.
And last but not least, it was the end of the road for the all-boy group Restless Road, who received the lowest number of America’s votes and were eliminated from the competition.
The country trio’s mentor, Cowell, offered some kind parting words. “I’m really disappointed, but you know what? I’ve said this before It’s not the end and you’ve been an absolute pleasure to work with,” he said.
The X Factor’s two-night finale airs Wednesday and Thursday (8 p.m. ET) on FOX.
