Elaine Jill Bickerstaff was born and raised in Barnet, Hertfordshire, where her father worked as an estate agent and her mother was a milliner. Her mother had been a singer in her youth, and her father was an amateur drummer. Paige stands at just under 5 feet (1.5 m) tall, which she says has caused her to lose out on leading roles. Her original ambition was to become a professional tennis player, at which point her headmistress pointed out to her "they'd never see you over the net", but Paige continued to play tennis and has referred to the sport as one of her passions.
