American Idol fans are in for a treat this week when season 11 runner-up Jessica Sanchez makes her debut on Glee!

If that wasn’t enough photo goodness for you, we are also getting our first look (via TVGuide) at Katey Sagal playing Artie’s mom on the May 2 episode of Glee titled “Wonder-ful.”

The official synopsis for this week’s episode of Glee titled “Lights Out,” according to a Fox press release, is as follows:

McKinley High loses power, and New Directions performs acoustically while electricity is unavailable. Vogue.com boss Isabelle Wright (Sarah Jessica Parker) recruits her former intern Kurt Hummel (Chris Colfer) to help out at a company-sponsored event to raise money for charity, with Rachel (Lea Michele) and Santana (Naya Rivera) along for good measure.

Though it might be the end of the road for season 4 in the next couple of weeks, Glee fans are excited as the series has been picked up for not one but two seasons! That’s right, seasons 5 and 6 of Glee are happening!
