Yes, like Chanel creative director Karl Lagerfeld (who bathes in a milky French micellar water) and Cleopatra (it's said that the Egyptian queen enjoyed the glow-enhancing benefits of the lactic acid), the chart-topping singer prefers soaking in milk, not water, for reasons unspecified. Hattenstone didn't press Carey on the topic any further, but we can't be the only ones who feel robbed by this teaser of an answer. Like other high-maintenance celebrity secrets, there's still so much more to this story that needs to be told, like what kind of milk Carey prefers (almond vs. oat vs. cow's)... and why would anyone choose to take a cold bath of any kind?
