The secret to Jennifer Lopez’s perfectly smooth and incredibly bountiful booty is out!

The 43-year-old, whose bangin' backside is one of the most famous in Hollywood, revealed the secret to her perfect posterior on Thursday night in Italy, taking to the stage in a skintight bodysuit that exposed her Spanx, and Breaking Celebrity News has the photos.

Leaving very little to the imagination in one of her nude, embellished Zuhair Murad catsuits, the singer’s stylists failed to notice that the outline of her less-than-sexy body shapewear was fully exposed.
