“The book, which details Carey’s romantic travails, her career ups and downs, the racism she experienced as a biracial child and much more, hit stores last week,” Billboard reminds us.

While some (seemingly including the magazine) may have thought the “UMAD” in Carey’s tweet was a jab at her detractors, it was no doubt a shoutout to her co-writer, veteran journalist, stylist and fashion activist Michaela Angela Davis, who helped bring Carey’s revealing and, at times, painful life story to the masses. (Davis is also known to many of her friends and followers as MAD—so Carey was essentially tweeting “Love u MAD.”)

Of working through Carey, Davis wrote: “There is beauty even through bleakness...celebrated like the family we have become.”
