X Factor judge Britney Spears stunned during the reality competition's Nov. 15 installment.
Spears, 30, took the stage in a low-cut, metallic mini-dress in order to stand by her team of teenage performers (which currently includes Arin Ray, Beatrice Miller, Carly Rose Sonenclar and Diamond White.)
Still, her smiley, gilded exterior belied some serious nerves, as she confessed to Us Weekly backstage Thursday.
"They are all so talented," Spears said of the contestants still in the competition. "This is their dream, so [our decision] is kind of crucial."
In the end, Simon Cowell's hip-hop group Lyric 145 and Jennel Garcia, of Demi Lovato's team, were sent packing.
