Jennifer Lopez was the lady of the night for the American Idol season 14 finale. The music veteran, who will launch her Vegas residency this summer, hit the stage for several performances. J.Lo, who donned a sparkly sheer dress, joined her judging peers Harry Connick Jr. and Keith Urban for an amazing performance of Rihanna's "Diamonds" and Bruno Mars' "Locked Out Of Heaven." She also teamed with Latin star Prince Royce for a sexy rendition of his new single, "Back It Up," which also featured Mr. Worldwide Pitbull.
