Jennifer Lopez Rocks Sexy Cut-Out Bodysuit At iHeartRadio Festival, Talks About Her Vegas Residency (PHOTOS)

At 46 years old, Jennifer Lopez still manages to be the sexiest performer wherever she goes. At the iHeart Radio Music Festival in Las Vegas on Saturday, Lopez stepped on stage in a white cut-out bodysuit, showing off all of her flawless curves, according to People.

The singer started the show off wearing a white, one-sleeved blazer over the revealing body suit, before changing into a sparkly vest that said "JLO" in gold on the back. She had her hair in tight braids and wore nude fishnet stockings.

While on stage, Lopez performed all of her greatest hits, including "On The Floor," "Booty" and even "Jenny From The Block," according to Entertainment Weekly.

With her Las Vegas residency starting in on Jan. 20, Lopez took full advantage of this opportunity to announce the official name of the show. The show, which will take place at Planet Hollywood Resort & Casino, will be called "All I Have," which is the title of her song with LL Cool J from 2002.

"I feel really blessed and I really plan to make something exciting," she told Billboard backstage. "Being in residency where you're just in one place - you can really dream. I think that's why there's so many great shows in Vegas. It's real treat for artists to be able to do a show like this. It's a much more intimate experience."
