She's undoubtedly one of the most gorgeous women in the world.

And on stage at the MGM Grand Garden Arena in Las Vegas last night for the iHeart Radio festival, the audience was left in no doubt that Jennifer Lopez is also one of the hottest performers around.

Donning a tiny criss-cross white leotard with nude fish-net tights, the 46-year-old wowed the crowd with her incredibly energetic presence. 

It seems that J-Lo is also eager to get in on another hot trend-of-the-moment: namely the thighbrow crease beloved of Beyonce, Rihanna and the Kardashian-Jenners.

Created when your thigh meets your hip, it allegedly looks an eyebrow, hence the name. And with the growth in popularity of high-riding swimsuits, it's pretty much all over Instagram right now.

Certainly, Ms Lopez's high-cut on-stage attire was perfect for embracing the look last night – and she even exaggerated the appearance of her thighbrow with the use of cleverly-positioned straps around her bum.

Also yesterday, Jenny From The Block announced that her forthcoming Las Vegas residency will be entitled, All I Have.

She kicks off the stint in January at the AXIS Theater and it is being billed as a "high-energy production," which features "Lopez’s iconic hit performances, as well as a combination of ballads, Latin music, funk and more".
