Lindsay Lohan is getting ready to go back in school!

We've learned exclusively that the actress will be filming her highly anticipated guest appearance on Fox's Glee this week.

So what are we hearing about Lohan's arrival at McKinley?

Sources close to the show tell E! News LiLo will start shooting later this week and that show execs have given her a "full scene," that will consist of one day of shooting. Oh, and it's "meaty."

Lohan will play a very important role in an episode set to air on May 15: a celebrity judge at Nationals! Yes, Lohan will be playing herself on the hit Fox show.

Her rep tells us, "Everything is running like clockwork and it's going to be a fantastic episode."

Lindsay's guest spot on Glee is just the latest step in Lohan's big Hollywood comeback: She recently hosted Saturday Night Live and is in talks play Elizabeth Taylor in a Lifetime movie.

Another celeb set to make a guest appearance in the final string of episodes? Whoopi Goldberg, who will be playing a recruiter for NYADA, the performing-arts school, in three episodes later this season.
