The male stars of Glee are all getting nervous about having to wear tiny gold pants for the Rocky Horror Show special, show creator Ryan Murphy has revealed.
The musical TV show, which stars Mark Salling and Cory Monteith as high school boys Puck and Finn, is devoting an entire episode of the second series to the cult classic, E! reports.
In the 1975 film, starring Tim Curry, Susan Sarandon and Richard O'Brien, the character Rocky emerges onto the scene wearing little more than a tiny pair of gold pants.
Ryan said the thought has made the Glee boys a little nervous.
He said: "All the boys [are] quaking in fear that they will have to wear the gold lame Rocky shorts."
In the episode, school counsellor Emma convinces Glee Club director Will to take on songs from the film.
Ryan promised there would be "more fun" for those two characters.
New arrival to the show John Stamos will take on the role of biker Eddie, played in the film by Meatloaf.
The new series of Glee is set to start in the UK in January.
