Kevin & Danielle Jonas Sit Front Row at Fashion Week
The Married to Jonas stars, who sat front row, took Danielle's younger sister, Katie, along to experience Fashion Week for the first time.
Then the trio headed over to The Daily Style Sessions where the girls stocked up on Chantelle Lingerie and Kevin snacked on Strawberry Fields Tic Tacs.
Kevin was overheard saying he and Danielle took it easy Monday night, while his brothers Joe and Nick went out to the Marc Jacobs after-party, an onlooker tells PEOPLE.
"He also mentioned how busy he and Danielle have been while filming their reality show," the source adds. "But he's excited about how it turned out."
Lauren Conrad, Gossip Girl's Michelle Trachtenberg, musician Alexa Ray Joel and Olympians Aly Raisman and Allyson Felix were also at the show.
