For those saying Keri Hilson although she looks good with the blonde and her hair has that T-BoZ feel she's way to tall and her voice is too light. Oh and I don't think age matters when playing them, TLC were like 20,21 when they're first record came out, they just looked younger because of their style of dress.

And I hope and pray that they will be using TLC's original vocals because I can't see them re-doing that. It just wouldn't sound right.
