Just when we thought Glee was finished shaking up its cast...

TV Line confirms that Ashley Fink, who plays the character of Lauren Zizes, will appear on the September 20 season premiere... only to abruptly quit New Directions and break up with Puck before the episode concludes.

Neither Fink nor a show spokesperson has commented on the development, though it's important to remember: the actress is not a series regular. She'll still appear on Glee, but only sporadically.

Still, many fans may be upset that Fink's screen time will be greatly reduced in favor of newbies such as the Glee Project winners and characters portrayed by Vanessa Lengies and LaMarcus Tinker.

Where do you stand? Do you wanna see more of Lauren?
