The Spice Girls became a pop phenomenon in the '90s, but now it's time for another British girl group to grab the spotlight. Mollie King, Frankie Sandford, Vanessa White, Una Healy and Rochelle Humes are The Saturdays, and they're taking over Sundays on E! with the series premiere of Chasing the Saturdays (January 20, 10/9c). "It's really important that everyone doesn't just see us as reality stars," says Frankie. "We want to make sure that everyone knows that we are a band, and that's why we're all together at the end of the day."
