Kendall Jenner, Hailey Bieber and Lori Harvey party in bikinis in Mexico

What to do when you're super sexy, rich and famous...hop on a yacht in your favorite bikini with some of your best friends, of course!!!

Kendall Jenner, Hailey Bieber, Lori Harvey and Justine Skye rented a beautiful yacht and dove into the blue waters of Cabo San Lucas on Thursday. Lots of smiles all around as the ladies soaked up some sun and splashed around in the ocean before having some serious girly time on board.

There was also plenty to drink -- courtesy of Kendall's 818 brand of tequila -- with a few bottles on the yacht and shots circulating.

No sign of famous boyfriends or husbands in the neighborhood, like Justin Bieber or Bad Bunny, but that didn't seem to matter at all...everyone was having a great time.

Remember, Kendall was recently spotted at the Drake show in Los Angeles with Bad Bunny and his sister,
