Lopes contributed her own self-written raps to many of TLC's past singles, including "Ain't 2 Proud 2 Beg", "What About Your Friends", "Hat 2 da Back", "Waterfalls", "No Scrubs" and "Girl Talk". Lopes was also a self-taught keyboardist and displayed those talents during her solo spot on TLC's headlining concert performances. She was also known for wearing a pair of glasses with a condom in place of the left eye lens in the beginning of her career, which was one of the ways she promoted safe sex. Lopes got the nickname "Left Eye" from a boyfriend who noticed that her left eye appeared slightly larger than her right.
