As previously reported, Michele will make an appearance on the June 5 season premiere, which is entitled "Individuality." Larsen, who tied with Damian McGinty in the first season of "The Glee Project," will be the guest mentor in the second episode, "Dance-ability," which will air June 12. Monteith will appear on the June 19 episode, "Vulnerability," and Rivera will be seen on the June 26 episode, "Sexuality."

The show features 14 young performers competing for a multi-episode guest-starring role on Fox's "Glee."

During the 11-week run of the series, according to Oxygen, “‘The Glee Project’ contenders will be narrowed down through intensive rounds of workshops, singing, dancing and acting-based assignments as the creative forces of ‘Glee’ carefully assess who has what it takes to be one of the next new faces of the award-winning show. Murphy will once again join casting director Robert Ulrich and choreographer and ‘Glee’ co-producer Zach Woodlee in the final deliberations of each installment of the series. Vocal coach Nikki Anders, who mentored the contenders on-air in season one, joins the judging panel in season two each week as a permanent member. Additionally, continuing with the format of season one, ‘Glee’ series regulars will appear on ‘The Glee Project’ as guest mentors.”

Winners of the first season of “The Glee Project,” McGinty and Larsen, were featured on the third season of “Glee” as foreign-exchange student Rory Flanagan and religious transfer student Joe Hart, respectively. The runner-up contestants of the reality series, Alex Newell and Lindsay Pearce, were given a two-episode spotlight on "Glee."

Michele, who stars as Rachel Berry on “Glee,” has been seen on Broadway in Spring Awakening, Les Miserables, Ragtime and Fiddler on the Roof. For more on Michele’s theatrical history, visit the Playbill Vault. To meet the contestants of "The Glee Project," click here.
