'X Factor' Contestant with Tourette's Wows Judges

By
The judges on The X Factor are accustomed to being in the presence of impressive talent, but a performance on Wednesday's show from a contestant with Tourette's syndrome leaves them with their jaws on the floor.
On Wednesday's episode of the reality singing competition show, Carlos Guevara, a contestant who's grappled with Tourette's since he was a child, takes the stage in hopes of passing the "Four-Chair Challenge" and advancing to the next phase of the competition.
With the goal of swaying mentor of the Boys category, Paulina Rubio, Guevara renders an awe-inspiring rendition of Bill Withers' "Ain't No Sunshine" rife with impressive range and spine-tingling falsettos.
While you'll have to wait until Wednesday to discover Carlos' fate, it's pretty evident from the featured sneak peek that Rubio is wowed by his performance, as she is rendered speechless with her mouth agape after he sings.
Watch Guevara's impressive performance of "Aint No Sunshine" as well as fellow Boys category competitor Carlito Olivero's rendition of Selena's "Dreaming of You" in the video above.
The X Factor airs Wednesdays and Thursdays at 8 p.m. on FOX.
