While on a luxury Memorial Day vacation, the whole Kardashian-Jenner family took part in the making of a music video -- even baby Mason! Check out the famous family as they lip-sync along to Katy Perry's 'E.T.'

"I’m so excited to finally present to you the Kardashian/Jenner/Odom/Disick/Humphries family music video," Khloe Kardashian blogged Tuesday. "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?!"

Simply put, this music video remake is pure gold. Where else can you watch the Kardashian-Jenners dance and sing while swimming and dining, enjoying the good life? Oh, yeah, that TV show...

Khloe adds, "I love my family!!!!" We love your fam, too, Khloe -- you guys sure do provide us with some great entertainment. This video is low-key, but is absolutely top-notch hilarious, and we know you're laughing, too ... All the way to the bank. Keep it up, Kardashians!

The 'Keeping Up with the Kardashians' season premiere airs on June 12.
