In the semi-finals stage of the show, the group performed Ellie Goulding's "Anything Could Happen" as well as Shontelle's "Impossible" for the second time during the competition. Their performance of "Anything Could Happen" was "a finals-caliber performance" according to Reid and described as "magic" by Britney Spears. However, their performance of "Impossible" received mostly negative reviews from the judges because the group had previously performed the song at Cowell's home (although not on The X Factor concert stage). Three members of the group (Camila, Lauren, and Ally) sang parts of the song in fluent Spanish. The following night's public vote results advanced Fifth Harmony to the final three along with Tate Stevens and Carly Rose Sonenclar. On the Top three live show, Fifth Harmony performed "Anything Could Happen" for the second time as their "Song of the Series" song. Their second song was a duet with The X Factor judge Demi Lovato singing "Give Your Heart a Break". Their final song of the night (and their last on the show) was "Let It Be" by The Beatles, billed as their "$5 million song". After the first round of the finals they did not receive enough votes from the public to advance to the Top two, and they finished in third place on December 20, 2012.
Throughout the months of July and August 2013, Fifth Harmony performed at various shopping malls across the United States in a promo tour titled "Harmonize America".
