Carey has kept busy with work amid her very public breakup from ex-fiance James Packer. Earlier this week, new details were revealed about the former couple's prenup negotiations, which is said to have dealt with everything from what's considered "gifts" between the two, to the use of Packer's private plane, to how much money Carey would have gotten for every year she was married to the billionaire businessman.
