Meet the actresses behind Mercedes and Tina on Glee:

Tina from Glee

Tina is the stuttering hidden gem in the club. Her speech impediment disappears the moment she starts singing and she brings the ‘bad girl’ edge to the group even though she’s nice enough to push Arty around in the chair whenever the choreography requires it.

Tina sang “I Kissed A Girl” by Katy Perry for her audition, complete with sign language.

Tina is played by Jenna Ushkowitz.
