Enrollment at McKinley High is ramping up! Jacob Artist, whose recent credits include Lifetime's "Blue Lagoon: The Awakening" and "Melissa and Joey," is set to play Jake Puckerman, Puck’s half-brother, according to Entertainment Weekly. Jake will try out for New Directions in the season premiere, but his no-good ways could keep him from singing and dancing with the club. (We know what a moralist Mr. Schue can be!)

But Puck's brother isn't the only new student on "Glee." With Rachel traveling to New York City for school, she gets an admirer. Dean Geyer, of "Australian Idol" fame, will join the cast as Brody Weston, an older classmate, who sets his sights on the new girl in town.

Other season four additions include Sarah Jessica Parker and Kate Hudson, who are slated to play mentors to Kurt and Rachel. No word yet on whether "American Idol" alum Jessica Sanchez, who had been rumored to be signing on for a mid-season arc, is enrolling at McKinley or NYADA.

"Glee" return on a new night—Thursday!—starting September 13.
