kardashian katy perry. Gang's all here! Move over Katy Perry, the Kardashian clan covered Perry's 'ET' in a sexy music video that's even got Bruce Jenner bobbing his head. The first family of reality TV filmed the video on a recent vacation and from Kendall and Kylie Jenner to Scott Disick and Kris Humphries to baby Mason, they all got in on the camera action.

Khloe Kardashian took to Celebuzz to blog about the family's latest home video: "I'm so excited to finally present to you the Kardashian/Jenner/Odom/Disick/Humphries family music video ... 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?!"

Talk about publicity gold for the family's forthcoming season premiere of 'Keeping Up with the Kardashians' on June 12.
