TLC members Tionne "T-Boz" Watkins and Rozonda "Chilli" Thomas will reunite for the first time in six years for the " Justin Timberlake and Friends" benefit concert Oct. 17 in Las Vegas, according to People.com.

T-Boz and Chilli have performed as TLC only once since Lisa "Left Eye" Lopes was killed in a 2002 car accident.

The two had sought a third member on a reality show called "R U the Girl?" A winner was selected but the duo stressed that they were not looking to replace Lopes but were inviting a singer to work with them on a one-off basis. No new material was released under the name TLC.

Timberlake's benefit concert also will feature Alicia Keys, Ciara and Taylor Swift, among others.

The concert, which benefits Shriners Hospital for Children, is part of a week-long charity event that includes the 2009 Justin Timberlake Shriners Hospitals for Children Open golf tournament, which runs from Oct. 12-18.
