The 'When She Was Mine' singers call it a "dream" to be performing at the music extravaganza today.
Lawson have taken to the stage inside London's O2 Arena to soundcheck ahead of their debut performance at the Jingle Bell Ball.
The 'Taking Over Me' stars donned their winter outfits on a chilly morning in the capital and have been Tweeting all week about their excitement for today's event.
Last night Ryan Fletcher tweeted: "Capital fm jingle bell ball tomorrow... What a dream gig been to see it for years and now we are gonna rock it's jingle bell balls off!!"
The band perform on a line-up today which includes the likes of Bruno Mars, JLS, One Direction, Rizzle Kicks, Cheryl Cole, Little Mix and The Script.
Tomorrow (9th December) will feature the likes of Pink, Girls Aloud, The Wanted, Rita Ora, Conor Maynard, Calvin Harris and Example.
