Perez Hilton, Rex Lee to Guest Star on GLEE, 5/15

As first reported on E! , blogger Perez Hilton and Entourage and Suburgatory favorite Rex Lee will sit beside Lindsay Lohan when she shoots her guest spot on GLEE later this week, playing a judge at the Nationals singing competition.

According to the report, Lohan will appear in the May 15 episode of GLEE as a judge for Nationals, and sources say she has some funny moments as she plays a "heightened" version of herself, including being disappointed she doesn't get a red chair that whips around like on The Voice.

E! also reports that Lohan has a long speech where she talks about kid performers, and how hard they work, and how much she supports the arts. "It's great stuff for her," says a source on the show. "She's been very nice to everyone."

Lindsay is shooting her scene this week on the GLEE set, along with Perez and Lee.
