Well yippie-kay-yay.

Kim Kardashian shared a series of pics from daughter North’s 7th birthday party (celebrated “Wyoming style,” as she put it) Monday evening on Twitter.

Kardashian’s husband, Kanye West, 43, sister Kourtney, 41, and the rest of her children — Saint, 4, Chicago, 2, and Psalm, 1 — make appearances at the cowboy-themed celebration.

West’s cowboy look could use some work, but then again, so could Kim, 39, and Kourtney’s: We can’t imagine there was a ton of maroon and turquoise leather at the OK Corral.

North’s celebration included a cowboy-hat shaped cake and a custom-painted ATV bedecked with horses. Among other details revealed by Kardashian’s tweet-spree: The family has a go-kart racetrack on their Jackson Hole ranch …

… as well as “14 gorgeous Freesians [sic].”

But North’s festivities were hardly the only big recent activities in Kim’s world: She also found time to dye her hair red!
