Jennifer Holiday re-emerges in a surprising performance with American Idol finalist Jessica Sanchez. The duo belt out the song made famous by Jennifer, "And I Am Telling You I’m Not Going".

I have to say, She still has it! She definitely is the original and I don't think anybody can come close. Bar those funny faces she makes during the performance, kinda scares me.
