The charity has a clinic in London but this money will help pay for a planned centre in Manchester.
Fans will be able to vote by text during the actual gig to decide which songs the bands play.
'It touched us'
Jenny from Atomic Kitten told Newsround's website: "We chose this charity because of the music connection, we really want to get involved. To set up a centre in Manchester will be a great thing for us because it's near our home towns."
