Nineties R&B super group TLC will perform at a concert in the U.S. for the first time in seven years, when the two remaining members reunite for a benefit concert hosted by Justin Timberlake this fall.

Tionne “T-Boz” Watkins and Rozonda “Chilli” Thomas, the two remaining members of TLC, will sing during the Justin Timberlake and Friends Concert — benefitting The Shriners Hospitals For Children — at The Mandalay Bay Events Center in Las Vegas on Oct. 17.

The group’s third original member, Lisa “Left Eye” Lopes, was killed in a car accident in 2002.

Tickets go on sale this Saturday.
