The businesswoman and reality star has been staying at her and her husband Kanye West’s $14 million Wyoming ranch.

Kim shared a family snap on Sunday in honor of Father’s Day as they posed at their ranch.

The star looked glamorous in a brown leather cut-out bodysuit with matching bottoms, adding a blue leather trench with futuristic sunglasses and large gold earrings.

Kim held on to their youngest child, son Psalm, 13 months, with North, seven, Saint, four, and Chicago, two, near her – as well as husband Kanye, 41, who wore a leather jacket and pants and a yellow T-shirt.

She also shared a snap of Kanye with his sons Saint and Psalm and his father Ray West.

She was in Los Angeles earlier this month to celebrate Scott Disick’s  37th birthday with a small birthday party that included Scott, Kourtney Kardashian, their kids Mason, Penelope and Reign, Kylie Jenner and daughter Stormi, Khloe Kardashian and daughter True, Kim’s kids and Kris Jenner – with just a handful of friends.

Kim looked incredible in a baby blue JBD Apparel crop top, called the Ion 2.0, pairing it with high-waisted denim and heels with her hair pulled half up, half down.
