Dance The Night Away! Jennifer Lopez gets frisky Las Vegas style as she hosts post-performance club night at Caesars Palace

After her rousing performance at the iHeartRadio music festival this weekend, it would have been rather a comedown to go straight to bed. And 42-year-old Jennifer Lopez clearly had no intention of hitting the hay as she continued the party at Pure nightclub inside Casars Palace. The star showed up in a form-fitting halterneck dress and proceeded to dance the night away to the delight of the crowd.
