The 28-year-old 'Glee' star has been cast as a single mother who works as a truck stop waitress, reported Digital Spy.
"I'm just now doing post-(production) on that episode, and she's great. She completely went there. Not a stitch of makeup.
"She's just a frumpy waitress. She really got it and embraced what the show was. I'm thrilled," he said, adding that Michele is a big fan of the drama, which helped in getting out a good performance from her.
The new season of 'Sons Of Anarchy', which will go air this month, also includes appearances from Marilyn Manson, Courtney Love, Malcolm-Jamal Warner and Annabeth Gish.
