Gleeks, you'd better make sure your DVR is set to 9:28PM ET on Apr. 13. Why? According to Fox, that's the official time when 'Glee' will return to the airwaves.

While its exact time slot may look a little random, it's likely the decision was made to accommodate 'Glee's' lead-in, 'American Idol,' a live show that has a tendency to run long.

'Glee' will return to its normal 9PM ET time slot the following Tuesday.

The news, along with an official episode description came from the official 'Glee' Facebook page. According to the description, Idina Menzel and Jonathan Groff will guest star in the episode, aptly titled 'Hell-o.'
