"Glee" creator Ryan Murphy informed E! Online that the Australian singing actress and ruthless cheerleading coach Sue Sylvester (Jane Lynch) will duet on John's 1981 single "Let's Get Physical." Lynch commented on the casting to E!: "I'm so excited I can't see straight! [Olivia] provided the soundtrack for my tortured adolescence. Her charitable work and commitment to making others' lives and the life of the planet better is so inspiring."
"Glee" is set to return with all new episodes April 13 at 9 PM ET. It has also been revealed that the ratings hit will seek out fresh talent to appear on the second season, which will air this fall. A multi-part special, which will document the casting for the three new "Glee" characters, will air as a pre-launch to season two.
