Watch Kim Kardashian & Kris Humphries Get Cozy in the Kardashian Music Video for "ET"

The family that lip-syncs together, stays together. The Kardashian krew had some fun in the sun on a recent family vacation where they made a cover music video to Katy Perry's "ET." Sisters Kylie and Kendall Jenner spearheaded the project, which featured the whole fam, and Kim Kardashian's new fiancé Kris Humphries, who seems to be fitting in perfectly.

"Hi dolls! Happy Tuesday!!!!! I hope you all had a fab Memorial Day weekend. I’m so excited to finally present to you the Kardashian/Jenner/Odom/Disick/Humphries family music video," Khloe Kardashian Odom wrote on her blog. "Kendall and Kylie are so creative and they always make music videos with their best friends Spencer and Madeline, but this time, they wanted the ENTIRE family to participate. We all learned the words to Katy Perry’s song ‘Extraterrestrial’ (even Bruce LOL) and then took turns lip syncing to it. My favorite part is where Masey is dancing. How cute is he?!

"I’m so happy Kenny and Kylie made this video — it’s so much fun for us to watch and it’s something we’ll always have. I love my family!!!!"

Kim shared on her blog: "The whole family went on vacation recently and Kendall and Kylie thought it would be fun to make a family music video to Katy Perry’s ‘ET.’ Even Mason took part, LOL. I loveeee this video!! Kendall and Kylie both directed and edited it! I can’t believe how great it turned out. They truly are geniuses!"

Kim and Kris — who went public with their engagement last week — got pretty cozy in the video, as they kissed on a kayak and danced with one another.

Kris also got down in the hot tub with Scott and Rob, showing he is one of the boys!

Catch the clip — which seems to be a nice way to promote the new season of Keeping Up With the Kardashians airing on June 12 —below!
