Cold Water Major Lazer feat. Justin Bieber & MO
From JLS to Janet - from Lily to Lady Gaga - it's not often you get so many of the world's biggest artists in the same place at the same time, and both nights of the Jingle Bell Ball give the Capital team a unique opportunity to interview the biggest names in music.
While we're getting ready for our interviews - we'll be broadcasting live from the O2 Arena on both nights and filming interviews with the artists backstage - we'd love you to get involved.
If you've got a question you're desperate to ask any of the artists performing this is your chance. Use the form below to send your question to us - and we'll put the best ones to the artists on the night.
Come on! What have you been dying to ask JLS, Janet Jackson, Lady Gaga, Miley Cyrus and all the other artists performing?
