Katey Sagal to guest on "Glee" as someone's mother...

Katey Sagal will bring some of her biker-badness to "Glee."

Show co-creator Ryan Murphy revealed on Twitter that the "Sons of Anarchy" star has joined the fourth season of Fox's musical hit to play Artie's (Kevin McHale) mother.

"So thrilled to announce my friend Katey Sagal is playing Artie's mom on Glee! There is nothing this woman can't do!" he tweeted late Thursday night.

Details are scant on how many episodes the former "Married... with Children" star will appear in, or when her run will begin, but McHale for one can't wait to get the mom he always envisioned for himself on the show, responding with the appropriate glee on his Twitter feed: "Wooo!"

According to The Hollywood Reporter, at last summer's Comic-Con, McHale said he always pictured Sagal to play the role of his mama (we guess her parenting skills on "Married... with Children" didn't worry him). While the role of his father has still not been cast, McHale apparently has an opinion on that matter too, saying that he would love to see Harry Connick Jr. in the role.

Sagal joins a long line of impressive parental figure guest stars on "Glee." Gloria Estefan plays Naya Rivera's (Santana) mother, Idina Menzel is coming back to play Lea Michele's (Rachel) mother, with Jeff Goldblum and Brian Stokes Mitchell as her gay fathers, and none other than Carol Burnett guested as Sue's (Jane Lynch) mommy dearest. Meanwhile, Victor Garber plays Will's (Matthew Morrison) dad, and Aisha Tyler has joined as Jake's (Jacob Artist) mother. That's a whole lot of famous mamas and papas.

"Glee" returns with all new episodes on April 11 at 9 p.m. ET on Fox.
