Word that Jennifer Lopez might be donning a lunch lady’s hairnet to scoop up a hot serving of Glee has the musical comedy’s young stars on a J.Lo high.

“It would be an awesome thing for our show,” Lea Michele, who plays Rachel Berry, tells PEOPLE of the possible guest appearance by J.Lo. “Series creator Ryan Murphy said he thinks she would be great to play a cafeteria lady that Kurt played by Chris Colfer gives a makeover to. And I think that’s hilarious!”

“It would be amazing to have Jennifer Lopez on,” said Amber Riley (who plays Mercedes Jones), adding the cast would welcome “anyone that’s been in it longer than we have that we can grab a little bit of inspiration from. And maybe some acting tips and singing tips.”

Lopez would be the latest in a series of high-profile guest stars lining up to appear on the show, including Olivia Newton-John, Idina Menzel and Kristin Chenoweth.

“If it actually happens, it’s insane,” said Kevin McHale, who plays Artie Abrams. “We had heard J.Lo say that Glee was one of her favorite shows, but the fact that she may come on? It’s incredible. … You don’t realize how amazing these are until you see them work with you … it’s just a learning experience like an acting class.”

Riley says Lopez isn’t the only A-lister who’s a fan of the show. A pair of famous women recently approached her to sing Glee‘s praises. “Fergie — that was crazy. She said that she really loved the show,” she said. “Also Sandra Bullock, she said she made her husband sit down and watch”

Matthew Morrison, who plays Will Schuester, says he got rave reviews from Harvey Keitel and Robert DeNiro, as well as one music giant that show’s been planning to go after: Bruce Springsteen. “The Boss came up to me and said, ‘I’m sorry, can I introduce my kids to you?’” Morrison said. “It was such a surreal experience. One of the writers, Brad Felchuck, was a huge fan of his, as am I. So we definitely want to get him on the show.”

But Morrison was a little too overwhelmed to seize the moment and extend an invitation. “I had a little star-struck moment,” he said.

Then there’s the superstar who tops Michele’s guest-star wish list: “Barbra Streisand,” she said with a reverent whispe — though she admits she’d be as tongue-tied as Morrison was with Springsteen. “I don’t know what I’d say,” she admits. “It would take a lot of thinking to figure out what to say.” –Scott HuverMatthias Clamer/FOX; Landov
