'Glee' set to pay tribute to Britney - again

'Glee' are making another Britney Spears-themed episode.

The hits of the new 'X Factor' judge - who made a cameo appearance on the show in 2010, drawing a record number of viewers for the musical drama - will be used in the second episode of the fourth series of the programme later this year, but the singer herself will not be in any scenes.
