Stunning ... curvy Kim sings into the camera

KIM KARDASHIAN looks out of this world in a bikini as she joins the rest of THE KARDASHIAN crew in a rendition of KATY PERRY's latest single.

The curvy star alongside sisters KHLOE and KOURTNEY are accompanied by their men, KRIS HUMPRHIES, SCOTT DISICK and LAMAR ODOM and half-sisters KYLIE and KENDALL JENNER in the hilarious three-minute clip, filmed for the new series of their E! reality show.

"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!!!!"
