All eyes on that booty and body! Jennifer Lopez performed alongside her fellow judges Keith Urban and Harry Connick, Jr. at the American Idol finale on Wednesday, May 13, but the focus was on the songstress, who wore a revealing, sheer gown.

Lopez, 45, looked sexy in the barely there number by Charbel Zoe, which included a sparkly bikini-style top and skimpy skirt that strategically covered her body. The piece included a faux jewel-encrusted halter neck, as well as a thin triangular cutout surrounding her belly button.

The star's latest body-baring number comes after she — along with Kim Kardashian and Beyonce — recently made headlines for wearing similar, underwear-free, sheer outfits to the 2015 Met Gala.

Lopez's performance on Wednesday included a cover of Rihanna's "Diamonds" and Bruno Mars' smash hit "Locked Out of Heaven." An observer at the live broadcast told Us Weekly that the performance was a lot of "fun," and included J.Lo "shaking a tambourine," while country megastar Urban (whose wife Nicole Kidman was in the house) shredded on his guitar as Connick, Jr. pounded on the piano.

The trio will return for the 15th and final season of American Idol in 2016.
