Madonna is planning another tour, and it may be her last, according to News of the World, so she’s looking into pulling in some special guests.

The singer is reportedly looking into having Glee stars Lea Michele and Cory Monteith appear in some manner on tour with her.

“Madonna wants to break records and make her career bigger than ever,” a source says.

“And because the Glee episode featuring her music was such a hit, there are plans for the cast to appear. She is in amazing shape for her age, but this could be her last big world tour she does for a while as she wants to concentrate on business ventures.”
