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.”
