Sierra Deaton is an American singer of British–Vietnamese descent, who is known as one half of the former indie pop duo 'Alex & Sierra.' She formed the duo with her former boyfriend, Alex Kinsey. The two made their TV reality show debut with the third and final season of 'The X Factor US' in 2013 and ended up winning the show. With that, 'Alex & Sierra' became the first and only duo to win the show's American version. Soon, Sierra and Alex were signed by 'Columbia Records.' They released their debut album, 'It's About Us,' in 2014. However, 'Columbia Records' later dropped the duo. They went on to release their first EP as an independent group. Sierra and Alex ended their 8-year-long relationship in 2017, citing professional stress as one of the reasons. Following the split, the duo disbanded. Sierra is currently dating Luke Hemmings.
