Where has TLC been? That question got answered on Saturday night in Hershey, PA when the two surviving members took to the stage for the 2nd annual VH1 Mixtape FestivalT-Boz and Chili didn't disappoint the capacity crowd and performed all of their massive chart hits including "No Scrubs", "Baby, Baby, Baby" and even dedicated "Waterfalls" to fallen member Left Eye before saying goodnight.

TLC are back in the studio working with the likes of Ne-Yo and other hit makers (album due in stores October 15th).  Look for the premiere of "CrazySexyCool: The TLC Story" October 22nd on VH1.
