This all-female trio scored a string of Top Ten R&B hits that established them as one of the most popular urban R&B groups of the '90s. Originally the name TLC was first intended for this group but TLC beat them by a couple of weeks to the name. Many famous singers have covered some of their hits such as Jojo, Christina Aguilera, and more recently Leona Lewis; who did a cover for today's Flashback Friday video.
