Will Justin Timberlake guest star on Glee?

“There is more than a little resemblance between Justin and Matthew Morrison… so the plan to bring Justin in for a cameo as his younger brother is a very popular idea. They are just trying to work it all out at the moment,” says a network insider.

It seems that everyone is excited about this new collaboration both fans and Glee actors.

“The cast members are very excited about the prospect of working with him – especially Lea Michele, so it has everybody’s seal of approval. They just need to work it all out now. The idea is that he will be a substitute teacher and join the glee club for a week.”
