Valerie Mahaffey, Jayma Mays, Don Most

Is it time for Will to meet Emma's parents?

Glee has cast Don Most and Valerie Mahaffey to play Rusty and Rose Pillsbury, the parents of guidance counselor Emma Pillsbury (Jayma Mays), TVGuide.com has learned exclusively.

It's clear now where our favorite obsessive-compulsive ginge may have gotten her red hair. Most is best known for playing the redheaded jokester Ralph Malph on Happy Days. Mahaffey has received an Emmy nomination for her supporting role as Eve on Northern Exposure and has a history of playing seemingly normal but rather intense (read: crazy) redheaded ladies, such as the Orson-loving Alma Hodge on Desperate Housewives. Hmm, "intense" could be a trait in the Pillsbury DNA.

Which Glee actress might be phased out in Season 3?

We're just wondering why Emma's parents will be visiting. Is it possible that she and Will (Matthew Morrison) could be getting serious?

As previously reported, in the same Tuesday, Oct. 4 episode, we'll also meet Mike Chang's (Harry Shum, Jr.) parents played by Keong Sim and Tamlyn Tomita. Now that promises to be an interesting Situ-Asian for Tina (Jenna Ushkowitz)!

Glee returns for its third season on Tuesday, Sept. 20 at 8/7c on Fox.
