3D is the fourth studio album by American girl group TLC, released on October 10, 2002, by Arista Records. Recorded from May 2001 to July 2002, much of the album was finalized after the death of member Lisa "Left Eye" Lopes, with her unreleased material that she had recorded for her solo albums Supernova and N.I.N.A. being reworked into new songs. Remaining group members Rozonda Thomas and Tionne Watkins enlisted Dallas Austin, Babyface, Rodney Jerkins, the Neptunes, Raphael Saadiq, Missy Elliott and Timbaland to work on the album.
