The 'Do It Like A Dude' singer even has the biggest dressing room backstage at the O2 Arena tonight.

Jessie J has admitted she finds it "very strange" that she will be headlining Capital FM's Jingle Bell Ball this evening (4th December)

A year ago, the 'Who You Are' singer failed to even get tickets for the event and is shocked that she is now headlining.

Speaking shortly after her soundcheck at the O2 Arena in London, she told Capital FM: "It's very strange. There's not been a middle ground because it's gone from not being able to get in to actually headlining."

Jessie also admitted that she will be taking some time to relax in her huge dressing room before she takes to the stage tonight.

She confessed: "I've been told I've got the biggest dressing room. I'm looking forward to chilling out in there and rearranging it like I always do."

Day two of Capital FM's Jingle Bell Ball will also see performances by JLS, One Direction and Ed Sheeran.

Capital FM will be coming live from the Jingle Bell Ball at London's O2 Arena all weekend. Keep checking for all the latest news, photo galleries and interviews from this year's festive spectacular.
