Front-row fussiness! Kim Kardashian revealed to Yahoo! Style why her baby daughter North West joined her famous parents front row at the Balenciaga show in Paris on Wednesday, Sept. 24.

"She started to cry when we were walking out the door [of our hotel]," Kardashian said of her 15-month-old tot. "And we couldn’t leave her. So, it was a spur-of-the-moment thing."

The pint-sized fashionista was photographed at the show, looking far less focused than the grown-up guests surrounding her. The entire family was decked out in head-to-toe black ensembles, with Nori supporting her dad Kanye West in a Yeezus top.

Kardashian, 33, told Yahoo! that her daughter thoroughly enjoyed her first fashion show experience. "It was an amazing fashion show for her to be at for her first show," the reality star said. "She loves it!"

Nori later stole the spotlight at Paris Fashion Week on Wednesday, when she was photographed confidently walking beside her mother outside of the Balenciaga show. (The tot took her first steps this past July after a swimming lesson.)

As reported by Us Weekly in August, little North has already developed her own sense of style. "Fashion is already a part of her," an insider told Us, adding that the famous baby had invented her own rendition of the Blue Steel.

"She loves the camera," the source said. "She always does a posed pout."

Her proud mom, meanwhile, revealed to Women's Wear Daily that Nori likes to primp herself. "North likes to brush her own hair," Kardashian said. "You start with a brush and then you have to get a second brush [for her]. Right when you get it all perfect, she takes the brush and starts doing it herself."
