Lea told Eonline:
“We’re doing [a] Black Eyed Peas song right now! We’ve been begging [executive producer] Ryan [Murphy] for such a long time to do one of their songs, and we finally just got one!”
In response to the song being featured Fergie told E!:
“Yes [I’m a fan of Glee]! I would love to do a [Black Eyed Peas] episode of Glee! And I would love to see them to the Peas—do us!”
So there’s no guarantee that Fergie will appear on the show, but given her willingness and the fact that Lea Michele said she would talk to show creator Ryan Murphy about the possibility of appearing on an episode, it could happen.
