Best known as a member of Atomic Kitten, one of the UK's most successful girl bands of the 21st century, Hamilton helped soundtrack an era with chart-topping hits that blended glossy pop with emotional candour. Now, she's returning to music on her own terms, reintroducing herself as a solo artist with the release of her new single, 'Numb'.
