The reality star, who is expecting her first child, beamed as she attended a fashion party with her husband Kevin Jonas.
Rocking glossy curled locks and minimal make-up, Danielle cosied up to pop star Kevin for most of the night. The eldest Jonas brother looked dapper in a green shirt with a contrasting blue collar and dark blue jeans.
The expectant parents, who confirmed last month that they were expecting a baby girl, were all smiles as they posed for a photo.
But Danielle and Kevin weren't the only glamorous couple of the night.
The pair were joined by Kevin's younger brothers, Nick and Joe, and their girlfriends at the party, which was hosted by US Weekly as part of New York Fashion Week.
While Danielle covered her bump in the frilly monochrome dress, Nick's beauty queen girlfriend Olivia Culpo looked glam in a red slinky dress with cut out detail to the shoulder.
Meanwhile Swiss model Blanda Eggenschwiler, who is dating Joe, looked effortlessly chic in a black LBD.
Kevin and Danielle, who married in a fairytale-themed ceremony in 2009, announced that they were expecting their first baby in July.
Sharing the news with fans, Kevin said at the time: "It's true @daniellejonas is pregnant! Can't even imagine how excited we are. I can't wait to share this with my best friend. I love you baby."
