‘Spotlight’ singer Jennifer Hudson turned heads rocking this Ralph & Russo couture gown with plunging neckline.  Taking center stage at the grand opening of The Smith Centre for the Performing Arts in Las Vegas this weekend, the Grammy winner reportedly brought down the house with her performance of ‘Take Care of This House’.

Joined on stage by Martina McBride, whom she also shared the stage with at the 2011 Grammys (in tribute to Aretha Franklin), see snaps of the divas in action below:

The two were accompanied by legendary singer/songwriter Carole King.
