Jennifer Lopez showed off her amazingly toned six-pack abs as she arrives at the taping for “American Idol” in a cutout Herve Leger dress that looked gorgeous on her. She completed her look with Guiseppe Zanotti heels and Pomellato, H Stern and Rene Sheppard jewels. The 42-year-old entertainer taped the live show alongside her fellow judges Randy Jackson and Steven Tyler. Jennifer may be going on tour this summer and bringing a very special guest: Enrique Iglesias. Although nothing is confirmed, but a close source revealed that the two “are in discussions.”
