What year is it again? Kim Kardashian and Paris Hilton team up for Hilton's new music video "My Best Friend's A**" featuring Dimitri Vegas and Like Mike.

Hilton's former assistant Kim K stole part of the show, with the ladies wearing matching dresses and Hilton singing about her best friend's butt.

Kardashian isn't the only celebrity cameo in the video. Other cameos in the video included UFC fighter Chuck Liddell, beauty YouTubers Nikita Dragun and Juanpa Zurita, former RuPaul's Drag Race contestants Nebraska and Derrick Barry, along with singer Chester Lockhart and prankster Vitaly.

The track was written by Vegas and the video was directed by Charlotte Rutherford. The music video's description reads: "The video is a satiric look on today’s VIP clubbing and social media life. When two fake Instagram-models enter the club and put on their “Insta-Goggles’, they transport themselves into a world of wild parties and beautiful people” popping bottles”, “ballin’” and “making it rain” – while the viewer can see what’s really going on in a world of selfies, filters, fake followers and likes… sound familiar?"
