Kendall Jenner Did the Unthinkable: She Smiled on the Runway at Paris Fashion Week!

Changing the game!

Helping to launch Paris Fashion Week, Kendall Jenner hit the H&M runway in the City of Light on Wednesday, March 4, and for once, she donned the one accessory you're never fully dressed without: a smile!

The rising model, 19, strutted her stuff down the catwalk in two printed ensembles—first, an emerald jumpsuit; then, a beaded sweater and rust pants. And while she was working both outfits, she did what models rarely do: She flashed a little smirk for the audience (which included Solange Knowles, Audrey Tautou, and Noomi Rapace, to name a few).

For beauty, Jenner, who also designs a line for PacSun, modeled tousled waves and a minimally made-up face—breezy and natural, the perfect reflection of H&M's casually chic clothing.

Despite her smile at the event, Jenner celebrated a decidedly different facial expression two days earlier, when she shared a photo via Instagram of her niece, North West, rocking a little baby snarl for the camera. The model's response to the tot's hilarious facial expression? "I feeeelllll you," she captioned.
