Singing competition shows may be on their way out, but the talent that they produce just keeps getting better and better. Though not every winner finds the same amount of success, the ones that do are the ones that are bringing something new to the table. Alex and Sierra, winner of last season's The X Factor, is fitting the bill perfectly.

The American pop duo is made up of Alex Kinsey and Sierra Deaton, and they became the first ever group to win The X Factor USA when the third season concluded back in December. They'll also be the last group, too, as it was announced that the US version of The X Factor will not be coming back for a fourth season following the departure of mentor Simon Cowell. Oh, and did we mention that Alex and Sierra are dating? Because that just makes it even better, and also pretty adorable. During their run on The X Factor, the two steamrolled through the competition with performances of songs like Taylor Swift's 'I Knew You Were Trouble' and One Direction's 'Best Song Ever, coming first in the public voting every single week. Alex and Sierra's charming on stage chemistry mixed with their impeccable vocals made it clear why they were the winners - and they might just keep up their winning streak when it comes to their new music as well.

Following their X Factor victory, Alex and Sierra inked a record deal with Syco Music/Columbia Records and instantly made a splash with their debut single, ‘Scarecrow.’ The song is upbeat and acoustic, and for the most part, it’s a pop adult contemporary dream; its lyric video currently has over a million views. However, when it came to sales and radio, it didn’t pan out exactly as expected. Despite a huge television performance on The Today Show promoting ‘Scarecrow,’ the song failed to chart on Billboard’s Hot 100 - an unfamiliar outcome for a group whose cover songs from The X Factor were pretty popular. Their Billboard flop isn’t a reason to sound the alarms yet, though. For what it’s worth, the previous two winners of the US X Factor didn’t have successful singles either. Season one winner Melanie Amaro had an album that never even saw the light of day; she’s no longer with her label. Season two winner, Tate Stevens? His self-titled record debuted decently on the country charts, but he quickly fell off when it came to subsequent single releases. Basically, despite winning a singing competition these days, it's hardly enough to keep you relevant; you have to have more than just a title to your name - and Alex and Sierra are showcasing that.
