Ellen DeGeneres spent her holidays on a "beautiful five star resort that could sink at any moment," also known as a yacht in St. Barth's. The host poked fun at her extravagant trip in the opening monologue of her show, calling the Caribbean island a "big fancy area where a lot of celebrities are during the holidays."A lot of celebrities, indeed. DeGeneres said she saw Leonardo DiCaprio, Justin Bieber , and maybe even a famous Orca whale, Free Willy. And what would be a A-lister vacation be without a Kardashian-Jenner sprinkled on top?
