Last July, it was revealed that Lea Michele will appear in one episode of the upcoming seventh and final episode of "Sons of Anarchy." And since the 28-year-old actress is best known for her role as Rachel Berry in the Fox musical series "Glee," fans have been speculating whether or not she will belt out a song in her guest stint on the hit FX crime drama series.

In an interview with Vulture, "Sons of Anarchy" executive producer and director Paris Barclay said that Michele did not get to sing in her one episode appearance, but he did ask her if she wanted to.

"Can't you sing a little something?" asked Barclay to the "Brunette Ambition" author. "But no, she wanted to stay in character, and I respect that," he said.

Michele will play Gertie, an empathetic truck stop waitress and single mother, who connects with Gemma (Katey Sagal) during a difficult time, and Barclay, thinks that her appearance on the show will give her some serious street-cred and allow viewers to see her as a versatile actress."Lea has never been on a show other than 'Glee.' I've directed a lot of 'Glees', so I've known her for a while. She's been very much identified with the character of Rachel," she told Vulture.

"When Kurt Sutter wrote this role, he said, 'Do you think we could get Lea Michele to do it?' And I said, 'Well, hell, let's ask!' And we did and she read it and within 24 hours, she said, 'Fantastic, I'm in,'" Barclay said.

But not all are pleased with Michele's casting on "Sons of Anarchy."A fan tweeted Sutter saying that the actress' addition to the show "sucks," but Kurt was quick to defend Michele, replying, "Look beyond the song and dance. The kid has chops."

Barclay also stood up for Michele, saying, "She only had to work one day, but she had to do six scenes, and she was awesome. The crew loved her. We finished early. She's so prepared."

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 late last month 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."

Barclay also dished to Vulture that Michele's character did not die, so he would love to see her again.

"Sons of Anarchy" Season 7 will premiere on Sept. 9 and Michelle will appear on the sixth episode titled "Smoke 'Em if You Got 'Em," which will air Oct. 14, Wetpaint reported.
