In this Yuletide edition Mo's joined by an all-star line-up of celebrity guests, including chart-topping singer Leona Lewis, TV Cupid Fred Sirieix, comedian and presenter Joel Dommett and star of People Just Do Nothing and The Curse, Allan Mustafa. The stars will take on a Christmas carol edition of Nursery Grimes, and Mo's studio audience get into a nationwide karaoke battle against Babatunde Aléshé's squad of partygoers in Manchester in a very merry Pass the Mic singalong.
