With her lively and outrageous performances of The Kinks' "You Really Got Me" and "Bring Me To Life" by Evanescence, the Puerto Rican songstress has stolen the show and become the one to watch this season.
Unfortunately, despite haunting renditions of REM's "Everybody Hurts" and K's Choice "Not an Addict," Zayra has routinely landed in the bottom three.
But since you never know what she is going to do, say (her sassy retorts to the judges' critiques are worth the price of admission alone) or wear next, fans are tuning in just to catch the latest episode of the Zayra show.
A fact that even the judges, Navarro and Lee, pointed out on this week's episode.
A mix of Blondie's Debbie Harry with the Yeah Yeah Yeahs' Karen O, Zayra's fashion forward ensembles (like the blue skin tight catsuit or her cape, gloves, and boots superhero trifecta) are a welcome change to the standard rock star uniform of black jeans, tank tops and wrist cuffs.
Zayra has the potential to become a musical fashion icon - think Gwen Stefani or J.Lo but edgier.
And if Zayra winds up on top at the end of the competition, the leggy Latina may find that the hardest part of the gig isn't winning but fending off Tommy Lee while on tour.
Check out Zayra Alvarez in all her glory on "Rock Star: Supernova" Tuesdays at 9pm on CBS.
