Middle DJ Snake feat. Bipolar Sunshine
Second to last out on the stage tonight, it's Marvin, JB, Aston and Oritsé!
It's that moment you've always been waiting for it's....JLS time! One question: can we start doing the 'Beat Again' dance yet?
And presenting....Oriste, Aston, Marvin, JB! 'Everybody In Love'! We've got our hands up.Oh yea!
Who's gonna do the first back flip? Our bets are on JB!
Best accessory - Oriste's MJ-themed black gloves or Aston's man-bangle?
"ELLA-ELLA!" It's 'Umbrella'! ELLA-ELLA!
First back flip? It was Aston!
"We recorded it for the album but it never made the album," says Marvin, time for the exclusive track 'Nobody Knows'
FACTOID! This is a cover of 1996 song by Tony Rich
Let's hope this doesn't make the lads dizzy.
Hurrah! We can do the 'Beat Again' dance now. Can we have one of those Madonna head mics too? FACTOID! Little Boots has done a cover of this track.
Ooh we hope they watch out for the low flying pyrotechnics!
Back flip #2!

JLS were on-form during their first night of their weekend Jingle Bell Ball residency, especially Aston and Marvin who delighted the ladies with their shirt-ripping antics.
