Kim, Kourtney and Khloe Kardashian's younger sisters created a music video for Perry's track with friends during a recent vacation in Wyoming.

Khloe posted the video on her official website, writing: "My little creative geniuses have done it again!!!!! Kendall and Kylie made another music video with their friends Spencer and Maddy and this one is definitely one of my favs.

"They cover Katy Perry's 'Firework' and they all do such an amazing job!!! My favourite part is definitely at the end when they pick Bruce [Jenner] up. Too funny!!! (sic)"

In a message posted on the YouTube video, Kylie and Kendall said: "Heres 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!"

This is not the first time the Kardashian family have covered a track by Katy Perry. The entire family - including Kim, Khloe and Kourtney - made a video for the singer's 'E.T' during a holiday earlier this year.

Posts on their official websites claimed that the video, which also featured Kim's fiancé Kris Humphries, Khloe's husband Lamar Odom and Kourtney's boyfriend Scott Disick, was devised, directed and edited by Kylie and Kendall.
