Apparently, the Kardashian clan has a big old crush on Katy Perry, because they keep doing cover videos of her songs!

After rocking out to “Extraterrestrial” earlier this summer, Kendall and Kylie Jenner are paying homage to Miss Perry once again, this time with a horse-filled video cover of her inspirational tune “Firework.” Alongside their two best friends Maddie and Spencer, Kendall and Kylie — with a bunch of fellas, cowboy hats and a whole lot of horse close-ups — lip-sync to the song.

On the YouTube post, the duo wrote: “Here’s our latest music vid! Just like our “Party in the USA” music video, this one was done in Wyoming! We go there every year with Maddy and Spencer, our two best friends that are in this video with us. Hope you guys enjoy!”

It’s been a fun-filled summer for the Jenner girls. Aside from their ranch-life vacation to Wyoming this weekend, they’ve been spending time living the laid-back California lifestyle many dream of. Recently, Kendall was spotted spending her July 4 weekend soaking up the sun on the Golden State beaches.

Earlier in the day on Sunday, Kendall posted a photo of the friendly foursome riding on horses in Wyoming.
