The Alex & Sierra singing couple auditioned for X Factor USA Season 3 in 2013, without realizing that they will turn into something big.
Singing sweethearts, Alex Kinsey and Sierra Deaton created funny moments during the interview with Simon Cowell before they performed.
Sierra was noticeably nervous, but Alex was there to hold her hand. Simon wondered why they want to sing Britney Spears’ “Toxic.”
The sweet couple sang a sultry version of the song, and they were entertaining more than expected.
And yes, Alex and Sierra won the X Factor USA Season 3 Finals.
