Shortly after, "CrazySexyCool" was released, selling over 23 million copies worldwide. However, Lopes' stint in rehab had led to her only having limited input in the writing and recording of the album. After the release of "CrazySexyCool", Lopes was a featured artist for the first time on "How Do You Like It?" a song by Keith Sweat in 1994. Later in 1995, Lopes was seen with TLC featured in "Freedom (Rap Version)" with other artists. In 1996, Lopes was featured on Lil’ Kim's "Not Tonight" (remix). TLC's third album, "FanMail", was released in 1999 and sold over 14 million copies worldwide. The album's title was a tribute to TLC's loyal fans and the sleeve contained the names of hundreds of them as a "thank you".
