After a school teacher suggested to her parents that her natural talent for singing and dancing should be nurtured, she was educated at the Aida Foster stage school from the age of 12, where she eventually became Head Girl. Her mother had to take an additional job to order to pay for the school fees. While training, she appeared in BBC Schools programmes. Webb later commented that, having come from a normal school, she found it a shock to be asked to perform in front of her classmates.
