If her speech alone wasn't enough to bag the songstress headline-worthy status, the 50-year-old reminded us all how great she looked in said dress.
Helping us to get into the festive spirit, Lopez sang a glorious rendition of 'Santa Clause Is Coming To Town' in a chic tuxedo.
Towards the end of the Christmas singalong, she hid behind a dance troupe and - virtual drumroll please - turned the stage into a runway thanks to the history-making Versace frock.
The moment was a sartorial tribute to her debut SNL hosting gig back in 2001 - where she also donned the now-iconic dress.
Showing her appreciation, Donatella Versace shared a clip from Lopez's original Versace television moment on Instagram.
"Jennifer on SNL in the original jungle dress in 2001, she is still so beautiful today, who can tell the difference!?" the designer wrote alongside the legendary clip.
During the early noughties television performance, Lopez joked about how her mum taught her to always be prepared. To demonstrate that she's taken on the life lesson, the singer whipped off her purple bathrobe to showcase the Versace gown beneath - a moment met with a roar of applause.
The dress has become one of 2019's biggest talking points after Lopez closed the Versace show in a revamped version of the leaf-emblazoned look she first wore on the 2000 Grammy Awards red carpet.
Proving that she still has serious sartorial influence, shopping app LIKEtoKNOW.it reported a staggering 1,200% increase in search for "green dresses" in the weeks that followed.
Hands up, who else contributed to the numbers?
