Alex & Sierra remind us of one of music’s most famous duos: Sonny & Cher. The similarities seem endless: You’ve got the obvious chemistry between the two leads, the long hair both Sierra and Cher rock, the use of ampersands! But do these two 22-year-olds have what it takes to become as iconic as the other crooning power couple?

We say yes! From the beginning, Alex & Sierra have wowed the judges with their simple yet show-stealing style.

It’s a style that can at first be deceiving. At their audition, judge Simon Cowell was skeptical the cutesy couple would be any good, saying, “I thought they were going to be terrible. Then they started singing and everyone, and most particularly Simon, was blown away by their rendition of “Toxic” by former X Factor judge Britney Spears.

“I thought it was an incredible version of the song,” said Simon, who later became their mentor.

Ever since that audition, it’s been nothing but blue skies and rainbows for 21st Century’s Sonny & Cher. Week after week they’ve lent their special vibe to numbers ranging from “You’re The One That I Want” from Grease to Ed Sheeran’s popular “Give Me Love” — a true standout moment for the pair.

If they keep this up, Alex & Sierra might have their own variety show by the end of the year.
