Kate Hudson and More Stars Celebrate Jennifer Meyer's Superga Collaboration in True Girls' Night Style

If Hollywood truly does have a cool kids club, members of it congregated inside L.A.’s iconic Chateau Marmont Tuesday night to celebrate Jennifer Meyer’s kickass collaboration with Superga. As the evening’s pack leader, Meyer showcased her youthful aesthetic in a printed black Saint Laurent dress with matching, heart-covered kicks from her new line. “I obviously do a lot of hearts in my line. So the heart is a piece of mine that I love so much,” she told InStyle of the print. “And it’s coming out around Valentine’s Day, and all seems like perfect timing.”

The print reflected the love between her and her friends, too. “She’s my best friend,” quipped Kate Hudson, who stunned in a colorful, graphic Etro jumpsuit. “We’ve known each other our whole lives. Then she’s just become this incredible designer and now it’s starting to expand. It’s just amazing. She’s doing so many collaborations and this is adorable. I’m proud of her. I couldn’t be more proud.”

With DJ Nikki Pennie spinning songs like The Weeknd’s “In the Night” and Notorious B.I.G.’s “Hypnotize,” the celebration’s atmosphere felt like a casual girls' night. In fact, friends definitely reunited and of course posed with Meyer. “She’s one of my closest friends in the whole world and I’m really proud of it,” Courteney Cox told us. By the way, she still feels like Monica from Friends. “I’m definitely Monica!” she quipped. “I’m not as competitive as Monica and I’m not as clean as Monica, but I’m very neat!”

For Demi Moore, who demonstrated how to rock overalls like an adult, the excitement was easy to read just from her killer smile. A stylish Jenna Dewan Tatum in a Suno was also on hand to sing Meyer's praises: “The thing about Jen is she can’t not be chic,” Dewan Tatum noted. “I’m the biggest fan of Jen Meyer. As a person, as a designer, in every single way. She’s like the coolest, baddest friend you wish you had in high school. She’s just all around pretty awesome.”

Maddie Ziegler, the 13-year-old Dance Moms star, was not only fond of the sneakers with “little hearts with arrows in them” ("They’re so cute," she said), but also of a kissing booth—perfect for A-list photo opps, like the one below with Meyer.

As for her designs, Ziegler for sure approves: “I love that her jewelry isn’t over the top, and it still looks like so beautiful, but it’s not flashy and it’s like very dainty, which is really cool.”
