It's almost here, Blujays! Hot on the heels of her new album release Jessica Sanchez is set to star in the season finale of Glee as New Directions rival Frida Romero. The episode "All or Nothing" airs tomorrow on Fox, but you can catch a glimpse of Sanchez in action below.

Sanchez describes Romero as "diva-ish" and someone who "struts her stuff."

"It's a fun role because I'm not really like that," Sanchez said.

Sanchez described working on Glee after being a fan for so long as "weird" but "so nice because they're so friendly and so fun and down-to-earth."

On top of this breakdown of life on the set, Sanchez finally reveals once and for all what songs she will sing as leader of the HoosierDaddies. Sanchez will be performing "Clarity" by Zedd and "Wings" by Little Mix.

Glee star Darren Criss was added to the list of people dumbfounded by Jessica's surprising vocals given her tiny frame.

"Is that voice coming out of that body?" he said. "That's amazing."

Sanchez even talked about her time beyond American Idol and her new album Me, You & The Music  before revealing that she's "ready to kill it for Glee and all the gleeks out there."
