Jessie J's amazing vocals stunned the crowds at the Capital Jingle Bell Ball - girl can SING!
Jessie J took it back to the old school with her classic hit song 'Do It Like A Dude' - and showed 16,000 people at London's O2 Arena exactly why she's a Jingle Bell Ball stalwart.
Jessie's first ever single is just as popular today as it was back in 2010 - and you guys have clearly had plenty of time to practise the lyrics and get them word perfect!
Jessie's live performances are always on point - and she blew the roof off the O2 with the bass!
