Before the 'Sons of Anarchy' star guest stars in a May 2 episode of the FOX musical series, 'American Idol' alumna Jessica Sanchez will appear in upcoming episode 'Lights Out' which airs April 25.
Katey Sagal's guest-starring appearance on "Glee" has been teased in a photo. Making its way out via TV Guide, the image gives the first official look at the "Sons of Anarchy" actress as Artie's mom. In a May 2 episode of the FOX series, Artie's mother comes to town with some big news about her boy's future.
Titled "Wonder-ful", the episode featuring Sagal will be a tribute to Stevie Wonder. Back on April 5 when announcing her gig on the show, the four-time Golden Globe-nominated actress hinted that she would be "singin' a tune or two."
Another guest star lined up in the remaining of the current fourth season is Jessica Sanchez. The runner-up of "American Idol" season 11 will be featured in "Lights Out" which will air this Thursday, April 25. She will play a student from a rival school described as a legendary diva powerhouse singer and her pictures from the episode have landed online.
FOX recently renewed "Glee" for season 5 and 6.
