Jennifer Lopez strips down to iconic Versace dress during 'SNL' opening monologue

Jennifer Lopez opened this week's episode of "Saturday Night Live" with a bang.

The triple-threat performer hosted "SNL" on Saturday night, and Lopez's opening monologue paid homage to her "unbelievable year," which involved her turning 50, going on a sold-out tour, her biggest box office opening of all-time with "Hustlers" and getting engaged to Alex Rodriguez.

"I got what every girl from the Bronx dreams of: Proposed to by a Yankee," she said to cheers from the audience.

Another moment from 2019 that Lopez called attention to? Her internet-breaking runway moment during Milan Fashion Week in September, which saw her wearing a reworked version of the iconic Versace dress that she wore to the 2000 Grammy Awards.

"I walked the runway in Milan for the first time wearing a dress I wore 20 years ago," she said. "Now, some people said I looked better now than I did then. And I'm not bragging! That's just, you know, gossip."

The singer, wearing a men's suit, then broke into "Santa Claus Is Coming to Town," performing an electric dance routine with the help of the Radio City Rockettes. At the end of the performance, she disappeared behind the dancers and re-emerged wearing the Versace dress again.

"I had to do it!" Lopez declared as the studio audience went wild.

Lopez's original 2000 Versace dress is heavily credited with being the impetus for the creation of Google Images, after the search engine saw record searches for photos of Lopez's plunging look at the time.
