Davida, Ashley, and Keisha fell in line after a series of successful auditions. The name TG4 is short for Tom Girls 4. "We're like four Tom Girls," said Amber, who tied for first place on Showtime at the Apollo when she was 10. "'When you're a girl and you act like a boy, you're a tomboy. We're girls and we act like guys but love being girls, so we're tom girls."
