Summarize this article about Priyanka and Nick:

Priyanka Chopra Jonas and Nick Jonas were giving cool-parent vibes at the Met Gala.

On Monday, the couple and parents of 15-month-old daughter Malti walked the red carpet together as they made their way up the iconic Metropolitan Museum of Art steps. For their parents' night out, the pair coordinated classic Valentino looks.

Paying homage to this year's theme, "Karl Lagerfeld: A Line of Beauty," Jonas wore a sophisticated suit — but with a tad of edge. The boy-band rocker opted for a leather suit jacket, layered over a crisp white shirt and a studded black tie.

"I think the black and white is a classic Karl look," the 30-year-old actor-musician told Vogue livestream hosts Derek Blasberg and Chloe Fineman on the red carpet. "You know, we're trying to play with a few of the jewels as well, obviously ... so I got a few of my own."

Meanwhile, Chopra Jonas, 40, wore a black strapless gown by the Italian luxury fashion house, featuring a big bow at the waist. The dress doubled as classy and sexy, thanks to its thigh-high slit that showed off her Valentino platform pumps.
In their Met Gala appearance, new parents Nick Jonas and Priyanka Chopra Jonas paid homage to Karl Lagerfeld in their chosen coordinating outfits. Nick opted for a suit with an edgy leather jacket, while Priyanka wore a black gown and white gloves to go with the black-and-white theme of the German designer.
