The first soundchecks have started on stage at the O2 Arena ready for this evening's huge event.
Olly Murs and Labrinth have both completed their stage soundchecks ahead of tonight's Capital FM Jingle Bell Ball.
The 'Earthquake' rapper is scheduled to perform at the Ball today (3rd December), on a bill that also includes Rihanna, Calvin Harris, The Wanted, Pixie Lott and Jason Derulo.
Olly also took to the O2 Arena stage this afternoon to prepare for his set, which will open the Jingle Bell Ball later today, and will include The Xtra Factor judge's popular single, 'Heart Skips A Beat'.
Labrinth is expected to debut several new tracks during his set, ahead of the launch of his debut studio album in 2012.
