J.Lo's coming up short!

Stepping out on the arm of her beau Casper Smart in Santiago, Chile on Monday, Jennifer Lopez showed off her newly cropped, shoulder-length hair that was done in a mane of wild curls.

Clad in matching black jackets and dark sunglasses, Lopez, 42, and dancer-choreographer Smart, 25, who have been publicly dating since November 2011, enjoyed some downtime before Lopez took the stage for her concert.

Lopez has been ditching her pin-straight strands for sexy, bombshell curls since the start of her multi-city tour, which kicked off on June 14 in Panama City, Panama.

Her hair, however, is overshadowed by her on-stage couture, designed exclusively by Zuhair Murad -- especially her nude, hand-embroidered crystal catsuit. The risque ensemble, reminiscent of Britney Spears' sparkly bodysuit from her 2004 "Toxic" video, was copied by Katy Perry at the Much Music Video Awards in Toronto, Canada on Sunday.
