"TLC is a musical trio formed in 1990 when Crystal Jones recruited Tionne "T-Boz" Watkins and Lisa "Left Eye" Lopez. The group was originally called "2nd Nature," but switched to TLC when Rozonda "Chilli" Thomas replaced Jones in 1991. (TLC is an acronym consisting of the first letter of each of the member’s stage names: T for T-Bonz, L for Left Eye, and C for Chilli). In 1992, TLC released its first studio album “Ooooooohhh... On the TLC Tip”. It was followed by “CrazySexyCool” (1994) and “FanMail” (1999), which peaked at number one in the US. Left Eye died in a car crash in 2002, leaving T-Boz and Chilli to continue on as a duo. As a trio, the band released several number-one hit singles including “Creep,” “No Scrubs,” “Unpretty,” and “Waterfalls.” Since Left Eye’s death, the duo has released two more studio albums, “3D” (2002) and “TLC” (2017). TLC was also featured in the VH1 biopic “CrazySexyCool: The TLC Story” in 2012.
