The brunette beauty is excited about forthcoming celebrity cameos in the US musical drama series but would love producers to approach the teenage singing sensation about a role in the show.
She told E! Online: "I don't know about Justin Bieber coming on the show, but he would be awesome.
"But I will tell you this—breaking news from Lea Michele!—we have an Academy Award winner coming on 'Glee' in the next few episodes that is not Justin Bieber."
However, the 24-year-old actress – who plays Rachel Berry in the show – is disappointed she won't get the chance to cosy up to Javier Bardem when he makes a guest appearance.
Speaking about the forthcoming appearance of the actor – who is expecting a baby with wife Penelope Cruz – Lea joked: "I know the storyline and it's not with me. Maybe I'll be like, 'Don't I look like Penelope Cruz? Hey, It's me—I'm Penelope.' "
Justin, 16, may welcome the chance to appear on the show alongside people of a similar age after recently confessing he finds life on the road can get lonely.
He said: "Lonely, yeah. I want to hang out with my friends, but I need security. I'm going to get my dog to come on the road in a couple of weeks."
