Having just filmed a guest appearance for the hit show, there is speculation that singer Britney Spears could appear again in 'Glee'.
Asked by 'Access Hollywood' if Spears would be back on 'Glee' again, the show's co-creator, Ryan Murphy, said: "Probably, yeah... probably."
Fans of 'Glee' will see Spears' cameo in the second series.
The Press Association says it is thought that her storyline involves a trip by some of the characters to the dentist, during which they hallucinate about the singer.
