Not Letting Go Tinie Tempah feat. Jess Glynne
Second to last out on the stage tonight, it's Marvin, JB, Aston and Oritsé!
OMG, JLS are making their second appearance at the Jingle Ball! We don't think we're ready for their jelly!
Lil Aston's wearing a cream jumper, aw bless. They're opening with Everybody In Love.
We're confused by Marvin's backwards hoodie though.
Ooh love heart ticker tape!
"You know JLS are looking for girlfriends, right?" Oh really Aston?! OMactualG. Next up is Umbrella!
"Wow London O2 how are you feeling tonight? This is such a special place for us, because we're from London. It's so great to see so many people here tonight, thanks!" Aw no worries Marvin!
We're loving JLS on this rotating stage!
It's a version of Tony Rich's 'Nobody Knows'!
"You know JLS are going to this time next year?" We can't wait for 2010! HAPPY BIRTHDAY JB! We're all singing 'HB' to him!
He's gone into the crowd and he's given his tag to someone. We're totes jealous!
Next up is 'Beat Again'!
We never get tired of this dance rountine. Look! We're doing it now!
JLS spoke to Roberto and Margherita before they become the only band to play both nights of the Jingle Bell Ball.
