Mere days ahead of the airing of the episode, a song featuring special guest star Gwyneth Paltrow on ‘Glee’ has leaked onto the net.

The guest spot sees Paltrow and ‘Glee’ star Matthew Morrison collaborating on a mash-up of Rihanna’s ‘Umbrella’ and classic ‘Singin’ in the Rain’.

Paltrow will be playing the role of a substitute Spanish teacher and Glee club coach when Morrison’s character, Mr. Schuester, gets sick. The episode, entitled ‘The Substitute’, will be airing on November 16.

Gwyneth’s ‘Glee’ spot is far from her only musical endeavour lately as the Oscar-winning actress recorded three songs for an upcoming country movie and also made her debut live performace at this year’s CMA Awards.
