TLC Performs at AMA’s With Lil Mama [Video]

TLC was back on stage last night at the American Music Awards. And, they invited Little Mama to step in and join them. Lil Mama recently  played Left Eye in the VH1 movie 'Crazy Sexy Cool The TLC Story.'  The performance was a little awkward. Most of the song was obviously lip synced which probably added to the non stellar performance. I don't have a problem with Lil Mama joining them on stage for Lisas' part. It made sense since she played Lisa in the movie. There are some fans though that didn't think Lil Mama needed to be in the performance. What do you think?
