In this week's episode titled "Smoke 'em if You Got 'em," Michele portrays Gertie, an empathetic truck stop waitress and single mother, who connects with Gemma (Katey Sagal) during a difficult time. The two characters share a cigarette together, and actually bond over their similarities.
In a recent interview with Vulture, the 28-year-old actress, best known for her role as Rachel Berry on the Fox musical dramedy "Glee," revealed that she is a big fan of the show, and perhaps that is one of the reasons why "Sons of Anarchy" creator Kurt Sutter wrote Gertie with her in mind.
"I know they wanted this character of Gertie to mirror a young Gemma," she added. "Katey and Kurt had me in mind for it, and I'm such a huge fan of the show - as he knows. I'm so glad that it all worked out. I found out when I was on vacation in Italy, and I was literally more excited about being on 'Sons of Anarchy' than being on a gorgeous vacation.
As to how she prepared for the role, the Golden Globe-nominated actress said she focused on Gertie's "mannerisms and the way she held herself and spoke." "Since I've played one character on 'Glee' for the past six and a half years, I wanted to make sure I played this character completely differently," she explained.
When asked how her shooting experience with Sagal was, the New York-born actress said that she had an "amazing" time.
"She's also been on 'Glee,' so it was fun to get to do her show," she said. "But I had to keep reminding myself that she wasn't her character. I'm literally so terrified of Gemma. I couldn't believe I was sitting next to her. I was like, Lea, remember, you're on a TV show, too."
"The character is so iconic," she added of Gemma. "She's a really fucking scary character, but Katey is so wonderful, and she made me feel so welcome and a part of the cast."
"Sons of Anarchy" executive producer and director Paris Barclay praised Michele's cameo appearance.
"She brought something totally different from Rachel," he told Hollywood Life. "I remember seeing her in 'Spring Awakening' when she was just a Broadway actress, and I knew there was a lot deeper actor there then what we have been able to use before or what we have seen on 'Glee.'"
Filming for Michele's guest appearance on the show went so well that she may be back for more.
"We love her," Barclay told E! News last August at BAFTA's annual pre-Emmys tea party at the SLS Hotel. "We're trying to find a way to bring her back. Her acting was completely naturalistic."
