"Absolutely stunning, flawless as always," one commenter wrote.
"Best dress of the night," another added.
J.Lo wore a glistening metallic look from Tom Ford and soft, brushed out curls inspired by old Hollywood glamour. The entire ensemble came together seamlessly with a smokey eye and stunning jewels.
