Hello, J.Lo! Jennifer Lopez went without underwear on the red carpet of the 2015 Billboard Music Awards on Sunday, May 17, where she again bared her incredibly sexy physique at age 45.

The mother of twins beamed outside of the MGM Grand Garden Arena in Las Vegas, in a long-sleeve, sheer gown by Charbel Zoe Couture that strategically covered her body in all of the right spots with crystal appliqués and embellishments.

Up top, the star bared her belly button and flat abs, as well as slivers of her bra-less cleavage. Down below, she revealed her underwear-free booty, which looked perkier than ever in the risque fashion number.

The star paired her smoldering outfit with dark and stormy eye makeup, and bronde balayage tresses styled to mimic a sultry bed-headed look.

"From where I'm looking from," noted E! News host Giuliana Rancic, "…it's basically strategic."

"This doesn't need taping," Lopez responded of her gown on the red carpet. "It's very well made."

The star, who recently signed on for a Vegas residency, spoke about her fellow superstars on Sunday night. "I've seen Celine, I've seen Shania, I've seen Britney. I love entertainment," she gushed, adding some notes about the final upcoming season of American Idol.

"It's been such a great experience for me," she said to Rancic. "I love the kids. I love the journey."

Finally, Lopez was asked about whether she had brought a date for the show that night. (Later, she was joined inside by Casper Smart.) The actress told Rancic that she was riding solo, staring down at herself and joking: "Here I am!"
