Forget Cowboys and Aliens. The Jenner girls make horsing around look like much more fun.

In a homemade music video to Katy Perry's "Firework," Kendall Jenner and Kylie Jenner get in touch with their inner cowgirls (and make friends with some cute cowhands).

"Just like our 'Party in the USA' music video, this one was done in Wyoming," they write on the video's YouTube description. "Hope you guys enjoy!"



Joined by friends Maddy and Spencer – but none of their Kardashian half-sisters – Kendall, 15, and Kylie, 13, ride horseback, rock cowboy boots and enlist the help of a few cooperative farmhands – all while lip-syncing along to Perry's pop anthem.

Making a cameo: dad and Olympian Bruce Jenner, who gets a pick-me-up from the girls for the video's finale.
