“Glee” creator Ryan Murphy has asked his cast members not to have sex in trailers on set.

In an interview with Heat magazine Murphy revealed that he didn’t want his cast members having sex with one another while at work: "I've dated people I've worked with and, you know, when you work on a set for 18 hours a day I think it's natural."

He added: "I have a rule: don't do it in your trailer! They've broken that rule on many occasions. I'm like, 'I know you guys are young and hormonal, but don't do it in your trailer'."

The Hollywood writer’s bold request comes in the wake of several rumors regarding the love lives of his cast members.

The popular musical comedy drama has witnessed huge success in the past year. Murphy has moved quickly to dismiss reports of a potential “Glee” feature film.
