The cast of 'Glee'

It has been revealed that there are plans for the cast of “Glee” to performs some of their hits on the U.S. version “The X Factor” later this year.

It is thought that the cast will take to the stage on one of the Sunday night shows for the end of the series.

People reported that a source had said “Glee on board is a real coup and everyone is very excited about it. Fans are going to be in for a real treat.”

The magazine also said that Simon Cowell is worming on the finer details of the appearance. He said “There are slight teething problems. Both X Factor and Glee's production teams want to be in charge of the set. Glee doesn't want [us] in charge - their brand is too strong to allow someone else to make decisions."
