Jennifer Lopez brought the sparkle to Mohegan Sun's 15th anniversary celebration this weekend straight from her “On the Floor” video! The beaded tulle Zuhair Murad bodysuit she wore on stage is the same look she rocked in her music video, originally released back in March. A custom embellished tuxedo dress by Rachel Zoe topped off the look. And Lady Lopez isn’t the only one with hot concert style.
