Nothing changes up someone's style more than a haircut!

Jennifer Lopez decided to switch up her look with shorter, curly hair. The American Idol judge had been sporting long, luscious locks for the duration of her judging stint. Whether or not she had some help from extensions, we will never know.

The 42-year-old was photographed in Santiago, Chile, on Monday with boyfriend, Casper Smart. J Lo looks decidedly different with cropped, curly hair.

It seems as if Lopez cut her hair twice -- once to about two inches below her shoulders and then again to shoulder-length.

Her hair is styled in a voluminous mane of wild curls. Despite the drastic change, she kept her caramel hue the same.

Lopez might have decided to change her style for her Dance Again tour with Enrique Iglesias. The 24-city tour kicked off on June 14 in Panama City and Lopez has been photographed bopping around South America flaunting her new hairdo beside Smart.

Lopez's tour is not only a nod to the singer's musical comeback, but it also recognizes her love for fashion.

Her tour costumes were designed by Zuhair Murad.

It is always exciting to work with Jennifer, Murad tells People magazine. There is no limit to her imagination and she is always open to new suggestions and

ideas. This tour was a new and challenging experience. My utmost wish is for each costume to create a 'Wow!' effect the moment she steps on stage.

The pieces for Lopez's tour, focused on Old Hollywood Glamour, will go perfectly with the singer's halo of curls. A blue feather cape, a mini dress and a black bodysuit with hand-embroidered black pearl beading and beaded fringe call for some untamed sexiness.

Murad and his team put excruciating detail into each of the tour costumes; specifically, 2,000 crystals or beads per piece. The costumes took one month to create, according to People magazine.

Jennifer has a beautiful body, he says, and wears each look perfectly.
