Kevin McHale and Katey Sagal

Finally, Katey Sagal gets a son without anarchy! The grande dame of FX's motorcycle drama rolls in to Lima, Ohio, for a guest spot opposite Kevin McHale on May 2's Glee. She plays Artie's mom, who comes to town with some big news about her boy's future. And the part-time chanteuse couldn't be more revved up about her role on the Fox series.

"Yay! Got a gig on Glee!" she tweeted April 5, hinting that she may even be "singin' a tune or two" in the episode, which showcases the music of Stevie Wonder. Signed, sealed, delivered, we're hers!
