Helen Mirren

Becky Jackson's inner monologue

Language Arts: "You may be wondering why I sound like the Queen of England. In my mind, I can sound like whoever I want, so lay off haters. I could easily snag any dude east of the Mississippi."
Attendance: Season 3, 1 episode: "Yes/No"
Glee Club Cred: No singing
Grade: B; Hearing her voice (as the inner monologue of co-head Cheerio Becky) was delightful, but we didn't actually see her face.
