Jennifer Lopez Wears A Tech-Savvy Dress On 'American Idol,' Looks Magical

"Jenny From The Block" no more -- just call her JLo, Queen of Outer Space!

On Thursday, the 45-year-old star performed her new single, "Feel the Light" during a taping of "American Idol" wearing a stunning white floor-length dress and skirt combo by Mariel Haenn. The custom-made off-the-shoulder gown featured a sweetheart neckline reached a 20-foot radius and 40-foot diameter -- almost the entirety of the "American Idol" stage!

But the best part of the dress? It acted as a blank canvas for a special effects light show. As the "Idol" judge belted out the tune from the "Home" soundtrack, lights, colours and special effects were projected onto the dress' giant skirt and train making for quite the epic performance.

Tune in tonight to watch this beautiful performance by @jlo and #TheDress #FeelTheLight #Home #Idol

According to stylist Rob Zangardi, who worked on the dress with Haenn, the look was inspired from an "old vintage reference" they had been "holding onto for a long time, waiting for the right moment."

Clearly, they picked the right moment!
