Rocking a bright red Tina Turner-esque mini dress, Jennifer Lopez performed "Jenny from the Block" and "On the Floor" at the two-day iHeart Music Festival in Las Vegas' MGM Grand Garden Arena.

After tearing up the stage, J.Lo, who changed outfits, spoke to "Extra's" Mario Lopez, who commented, "This is not what you were getting down in a minute ago!" Jennifer replied, "No, no, no... I had a little fringe action going on."
