Hudson vs. Holiday: Who Can Scream The Loudest?!

First off, you gotta give honor where honor is due. Jennifer Holiday is the original DIVA of this song and can sing the melody right out of it. Jennifer Hudson surprised her Atlanta audience at her and Robin Thicke's show last night by bringing out the lovely Ms. Holiday. Of course they kinda did a duet to her famous song "And I Am Telling You"(I'm Not Going). Is it just me or is it that when these two get together it almost sounds like a contest? Is J Hud just trying to keep up with the powerhouse voice that is Jennifer Holiday? You be the judge.
