Check out this hilarious clip of Corin and Andrew rehearsing for their duet in front of the Big Brother live crowd tonight.

As part of yesterday’s Glee task, the housemates took part in a duets master class with Andrew Stone and he chose Andrew and Corin to perform a special rendition of Time Of Our Lives on tonight’s live show.

If they complete this part of the task then housemates will succeed in this week’s shopping task.
