Ummm, okay...

Lea Michele is trading in the glee club for a biker gang on Sons of Anarchy. The Glee star tweeted the news that she'd be appearing the final season of the FX drama with a guest role.

"I'll be appearing on an episode of my favorite show @SonsofAnarchy! Thank you so much @Harparbar & @sutterink #SOAFX," she tweeted and included a photo. The people she thanks included Paris Barclay, a director on both Sons of Anarchy and Glee and SOA creator Kurt Sutter.

Michele will play Gertie, "an empathetic truck stop waitress and single mother, who connects with Gemma during a difficult time," a rep for FX told E! News.

This isn't the first time Glee and Sons have bled together: Katey Sagal, Sutter's wife and star of Sons of Anarchy, plays Artie's (Kevin McHale) mom on Glee.

Sutter took to Twitter and teased a casting announcement before Sons of Anarchy's Comic-Con panel, but no news was revealed.

Other guest stars for the seventh and final season of Sons of Anarchy include Courtney Love, Marilyn Manson and Walton Goggins. Love will play preschool teacher Ms. Harrison. Manson will play "Ron Tully," a white supremacist prison leader who Jax (Charlie Hunnam) encounters.

Sons of Anarchy's final ride kicks off Tuesday, Sept. 9 at 10 p.m. on FX.
