The triple threat donned a jaw-dropping Balmain dress at the star-studded annual fashion event on Monday.
The couple made their joint debut at the 2017 Met Gala and returned to the high-fashion event on Monday night to slay yet again.
Lopez, 48, stunned on the carpet at the Metropolitan Museum of Art's annual star-studded fashion event, rocking a jaw-dropping Balmain gown that embraced the theme of the evening, “Heavenly Bodies: Fashion and the Catholic Imagination.”
The triple threat’s dress featured intricate beading in blue, black and red, with a massive cross on her chest with open shoulder cutouts. The long black, feathered skirt accentuated her long legs, with a high slit up the left side.
The couple stopped to chat with ET’s Keltie Knight about their time together since their public debut. Rodriguez called the year “awesome,” while Lopez agreed, saying it had been an “amazing year.”
“A lot has happened,” the former New York Yankee told ET, before pointing to his date’s edgy ensemble. “This is gorgeous. I couldn't believe it when I first saw her today.”
With all the love in the air, could these two be heading down the aisle anytime soon?
“Royal wedding?!” Lopez teased when asked if this American royalty would be tying the knot. “There's a royal wedding coming up! There's a royal wedding coming up.”
The Shades of Blue star wore her shoulder-length hair slicked down, and completed her look with black heels, a black bag, and diamond earrings.
The pair were all smiles as they posed for pics together. Rodriguez, who donned a dapper all-black suit, even had Lopez breaking out into adorable giggles at one point on the carpet.
They were also spotted in entirely different looks, leaving the after party at the Boom Boom Room at the Standard Hotel following the glam event. For the more casual affair, Lopez work a sequin mini-dress and scarlet heels with furry accents. She covered up in a black feather-lined coat.
The power couple have been going strong for over a year now, and Lopez recently opened up about her relationship with Rodriguez and how it centers on their modern family. The actress and singer shares 10-year-old twins, Emme and Max, with ex-husband Marc Anthony, and her beau has has two kids of his own, daughters Natasha, 13, and Ella, 10.
"For me, he's so lovely and he's so supportive and encouraging of everything that I do," Lopez gushed to ET at the World of Dance FYC event last week. "I'm glad that he sees me that way, that I would be a good role model to his girls. You know, I'm just trying to be a good mom to mine and the best I can be for all four of them."
