It’s the last chance for Lauren Jauregui, Camila Cabello, Ally Brooke Hernandez and the other members of Fifth Harmony to prove they have The X Factor…

During Wednesday night’s performance episode of Fox’s singing competition, the top three acts gave it their all in an attempt to garner America’s votes and win a $5 million recording contract.

Long considered long-shots to make the finals, Simon Cowell’s manufactured all-girl group, returned to the stage after knocking out Emblem3 in the semi-finals to prove they belonged on the stage this week.

For their first performance, Jauregui, Cabello, Hernandez and the other members of Fifth Harmony performed Ellie Goulding‘s “Anything Could Happen,” which they sang last week. As before, they’re at the Mad Hatter’s tea party, but this time they amped their performance with some extra mad over the top production values, including a giant back-screen projection of Pegasus.

“Now I’m looking at it and it’s magical,” says L.A. Reid, while Britney Spears gushes that the magic happened when the girls sang the song.

“I really hope that America pulls through and votes for you guys,” said Demi Lovato; and Simon commented, “You’ve made me so proud tonight, girls.”

For their second performance, the all-girl group performed The Beatles‘ classic “Let It Be“.

Reid syas the girls did “a lot of justice” for the song. Lovato liked that the group has evolved.

In addition, Fifth Harmony performed Demi Lovato‘s “Give Your Heart a Break” with the 20-year-old half-Mexican American singer joining in midway through the song. Cowell called it “pop perfection.”

“I love you guys,” said Lovato about performing with the girls. “It was so much!”

The winner of “X Factor” season two will be revealed on Thursday, December 20. Pitbull and One Direction are all set to perform at highly-anticipated the final result show.
