a. Not pretty.
Wikipedia
"Unpretty" is a song by American recording group TLC. It was produced by Dallas Austin and co-written by Austin and TLC member Tionne "T-Boz" Watkins in August 1998 for the band's third studio album, FanMail (1999). Long time contributor Dallas Austin helped Watkins adapt the poem into an empowering song for their female fan base to overcome feelings of physical inadequacy.
"Unpretty" was the second single released from FanMail. It became the group's fourth US number one single on the Billboard Hot 100, spending three weeks atop the chart, and the second consecutive number one single in from the album, following " No Scrubs". A critical success, the song was nominated for Song of the Year and Best Pop Performance by a Duo or Group with Vocal at the 42nd Annual Grammy Awards. A remixed version of the song, sampling Dennis Edwards & Siedah Garrett's "Don't Look Any Further", was produced by JayDee of 1208Ent. and "Mad" Mike Lewin. Two versions of the remix were made, one containing a rap verse by Lisa "Left Eye" Lopes and one without the rap.
