What started as a rumor has now been confirmed as a casting fact:

Katie Couric is coming to Glee. The CBS Evening News anchor will make a cameo as herself on the show's February 6 Super Bowl episode. Said a source to The New York Post:

"The deal is done, and Katie will make a cameo as herself. It will be filmed very soon."

Look for Couric to appear in a scene with Jane Lynch as Sue Sylvester.

Elsewhere, Glee fans are buzzing over Ryan Murphy's recent admission: many cast members will exit after 2012 season, as their characters graduate and New Directions moves on.
