During their vacation to the Dominican Republic, Kim, Kourtney, Rob, and the rest of the Kardashian and Jenner families let loose by covering the Notorious B.I.G.’s “Hypnotize.” The reality stars each took turns mouthing the lyrics to Biggie’s classic on board a private yacht. Kanye’s bikini-clad girlfriend showed off her assets, Kris and Bruce got their freak on, and Scott rubbed his pregnant wife Kourtney’s belly.

The video came with the following disclaimer: “heres our latest family music video to Hypnotize by Notorious B.I.G.!!! we might get some hate but who cares, we had fun doing it! hope you guys don’t take this too seriously! 😀 love you allllllll!!!! ENJOY.”

Watch E!’s First Family bond over some Biggie.
