The former Glee star is set to replace actress Kimiko Glenn when the Orange is the New Black regular takes a leave of absence at the end of the month (Jul16).

Jenna will take on the role of Dawn, a waitress at a small-town diner, alongside the show's leading lady Jessie Mueller and co-star Keala Settle.

While she's best known for playing Tina Cohen-Chang on Glee, Jenna made her debut on the Great White Way at the age of nine in the 1996 revival of The King and I, and also appeared in the original run of Spring Awakening in 2008.

Jenna begins her stint in the musical on 29 July (16).

Waitress, based on the 2007 film of the same name, features a score from singer/songwriter Sara Bareilles and was nominated for four Tony Awards this year (16).
