Doja Cat is pretty well known for thinking outside of the box, so it's no surprise that she got creative with her 26th birthday, choosing to host an underwater Atlantis-themed costume party. On Wednesday night, the "Kiss Me More" rapper [1] gathered some of her closet friends to join her for the Hollywood undersea celebration, including a few famous faces like Billie Eilish [2], Normani [3], Karrueche Tran [4], Hailey Bieber, French Montana, and more. Doja's costume was the highlight of the night, as her Princess Kida outfit [5] was super spot-on — even down to the face paint, crystal necklace, and giant spear. And her party guests seemed just as enthusiastic about the theme as she was. Ahead, get a glimpse of some of the stars who stepped out for the aquatic affair.
