Kylie Jenner mocks the paparazzi at Kris Jenner’s 70th birthday party

Kylie Jenner wasn’t there for the paparazzi flashes Saturday night, but she made sure to handle it the Kardashian-Jenner way, with style, confidence and a bit of attitude. The beauty mogul was pictured mocking photographers as she arrived at Kris Jenner’s 70th birthday celebration, proving once again that when it comes to grabbing attention, no one does it like Kylie. The Kylie Cosmetics founder turned heads as soon as she pulled up to the event, flashing her middle finger from inside her car as paparazzi flocked to get a glimpse of her.

Despite the cheeky gesture, insiders told TMZ that Kylie wasn’t upset. She was just feeling sassy and having fun.

Dressed to the nines for the ultra-exclusive evening, Kylie looked radiant as she joined hundreds of Hollywood elites to celebrate her mother’s milestone birthday. The floor-length dress featured a backless neckline with a structured collar that wrapped around her neck, creating a sculptural silhouette. The form-fitting bodice cinched in her waist before transitioning into a smooth, draped skirt that showed off her curves.

Adding a bold touch, the dress included bold side cutouts that accentuated her silhouette, giving the otherwise classic look a modern, high-fashion twist. She styled her hair in a soft bun with loose tendrils framing her face and kept her accessories minimal, letting the sleek, sculptural dress do the talking.

The overall look captures Kylie’s signature blend of sophisticated glamor and confident attitude, making it one of the most talked about ensembles of the evening at Kris Jenner’s 70th birthday party.
