Kourt’s ready for her "klose" up! On Wednesday night, Kourtney Kardashian flaunted her assets in a sexy secret photo shoot, which she documented on her Snapchat.

“Shooting something top secret, cover!” Kourtney teased with one of the photographers.

The camera also caught a makeup artist taking a brush to the mother of three’s butt.

“Alright, we’re doing a little booty highlight,” she said.

“You’re ass is looking good, Kourt,” the artist replied.

Kourtney posed in bed wearing white boy shorts and a white cropped tank top. In one racy Snapchat, the camera panned up over her body as she grinned from the sheets.

But the eldest Kardashian wasn’t alone. Her younger sister Kim Kardashian came along for some moral support.

“So I’m on set today, but it’s actually not a photo shoot for me for once. It’s for one of my sisters, and she stole my glam team,” Kim exclaimed from her own Snapchat.

Kim posted a photo of her own look, which included thigh-high lace-up boots. She later Snapchatted a precious picture of her baby son Saint’s hand.

The two sisters have been spending a lot of time together recently, visiting Cuba earlier this month and traveling to Iceland in April to celebrate Kourtney’s birthday.
