She's got a healthy glow to her olive complexion that would instantly be amplified in the desert climate of Las Vegas, Nevada.

But Jennifer Lopez made sure her curves got the maximum attention as she stepped out in an entirely white outfit today.

The former American Idol judge celebrated her Enrique and J-LO World Tour with a special appearance and pre-party at Wet Republic Ultra Pool at The MGM Grand Hotel and Casino in Sin City.

She wore a matching crochet ensemble which consisted of high-waisted shorts and a cropped top which allowed her belly button to be visible.

From behind, the item even showed off her sculpted back, although much of it was covered up by her highlighted locks which were pulled back into a half-up-half-down style.

The 43-year-old star emphasised her toned pins by ditching the sunbathing staple of flip-flops and wearing snakeskin heels instead.

Jennifer was accompanied by her beau, backing dancer Casper Smart; however he didn’t pose with her and was simply there to hold her hand in support.

Her toyboy, 25, looked noticeably younger than his partner in his casual get-up.
