2013: The X Factor Alex & Sierra auditioned in
New Orleans,
Louisiana, making it to the next round after wowing the judges with a sultry version of
Britney Spears' "
Toxic". They continued on to the top 40 and received
Simon Cowell as their mentor. For the Four Chair Challenge, Alex & Sierra took on the
John Travolta/
Olivia Newton-John classic "
You're The One That I Want" from the 1978 musical film
Grease. The judges praised the duo for putting their own twist on the song.
Kelly Rowland and
Paulina Rubio felt the performance was "nice" and said they had "sexiness" to them, while
Demi Lovato told them they were one of their favorite acts but questioned the future and their relationship. Despite this controversy, the duo made it through to the live shows. For the first live show, Alex and Sierra earned a spot in the top 12 after performing a stripped-down version of the
Robin Thicke hit "
Blurred Lines". Kelly Rowland wished it had been a bit sexier and thought it got corny at times, something Simon Cowell disagreed with, For Motown Night, they took on "
I Heard It Through The Grapevine" by
Marvin Gaye. Paulina felt it was "natural," while Demi said it felt "organic" as well as very "hot" and "sexy". On the re-vote show, which happened due to a graphics error that nullified the votes, Alex & Sierra sang "
Give Me Love" by
Ed Sheeran; Cowell afterward said that the performance was "immaculate... ragged and raw." For '80s Night, the couple took on the
Robert Palmer classic "
Addicted to Love". The performance earned them negative reviews; Kelly wanted them together more, Paulina called them "Bohemian" and "vintage", Demi felt that Sierra looked uncomfortable in her shoes and wanted the performance more organic, and their mentor Simon expressed disappointment over how the performance went by saying that they lost the melody in the beginning and "it wasn't as good as it should have been." However, Sierra's vocals were criticized for not being as strong as Alex's. Their version charted on the top 40 of the US iTunes, the first act to do so that season. For Divas/Unplugged night, the couple sang two songs. Their "Diva" song was "
Say My Name" by
Destiny's Child. The song earned them praise from Kelly, who said she adored the new sassy side of Sierra. Their "Unplugged" song, "
Say Something" by
A Great Big World and
Christina Aguilera (thought by many as their best X Factor performance) earned them praise by the judges; Kelly said she felt like she was watching an awards show, Demi felt that the performance was "magical", Paulina was impressed with Sierra's talent with the piano, and Simon stated that this was not only their best performance of the night but of the season. For the semi-final, the public chose "
Little Talks" by
Of Monsters and Men, which pleased the judges; Kelly said they nailed it, Demi felt they were looking at the winners, Paulina said that they kept coming back stronger and suggested that there was a huge gap in the industry for them, and Simon said they were not just performing - they were making records each week. They faced
Carlito Olivero in The Duet Duels singing "Falling Slowly" with the judges feeling that while Carlito and Alex did well, Sierra stole the song. They also sang "
Bleeding Love" with
Leona Lewis, and their "song of the season" was "Say Something". The "Bleeding Love" performance received a bit of a mixed response mainly from Demi Lovato, who said that it wasn't their best performance, but the other two songs received praise. In the finale result show, Alex & Sierra performed "All I Want For Christmas Is You". Later that night, they were announced the winners of the season on December 19, 2013. They were the only group to win the American version of the show. In an interview after the winner was announced, Simon Cowell revealed that Alex and Sierra received the most public votes every week of the competition. He said that the margin for the number of votes narrowed closer to the end of the season.
