Could these two be more adorable? Alex, 21, and Sierra, 22, wowed the X Factor judges on Week 1, Night 1 of auditions with their rendition of “Toxic” by former judge Britney Spears.  Not only did they win their way into the hearts of the judges, but also the next round.

(If you’re curious whether they make it into the top 16, click here!)

Alex and Sierra are two college students from Orlando, Florida, who have been dating for two years. New judge Kelly Rowland could tell immediately they were in love, and we have to agree. These two cuties make some beautiful music together — but we don’t just mean that euphemistically. On top of the fact that they’re an adorable couple, they also make an excellent singing duo. If you don’t believe us, you’ve gotta check out their audition.

If their acoustic take on the popular Britney hit sounds familiar to you, you might be a fan of The Voice. Season 3’s Melanie Martinez performed a very similar arrangement during the Blind Auditions round (and had similar success with it). In fact, Sierra’s voice reminded us an awful lot of Melanie’s!

What do you think of these two? Sound off below!
